Welcome to Wikidata, Leiem!

Wikidata is a free knowledge base that you can edit! It can be read and edited by humans and machines alike and you can go to any item page now and add to this ever-growing database!

Need some help getting started? Here are some pages you can familiarize yourself with:

Introduction – An introduction to the project.
Wikidata tours – Interactive tutorials to show you how Wikidata works.
Community portal – The portal for community members.
User options – including the 'Babel' extension, to set your language preferences.
Contents – The main help page for editing and using the site.
Project chat – Discussions about the project.
Tools – A collection of user-developed tools to allow for easier completion of some tasks.

Please remember to sign your messages on talk pages by typing four tildes (~~~~); this will automatically insert your username and the date.

If you have any questions, don't hesitate to ask on Project chat. If you want to try out editing, you can use the sandbox to try. Once again, welcome, and I hope you quickly feel comfortable here, and become an active editor for Wikidata.

关于阁下在talk里谈到的

中文维基百科连接时断时续，所以在这里回复阁下了，毕竟也和wikidata有关

1，别孕烷二醇那个应该是英文弄错了，在下原先发现结构图是错的，之前在commoms更改过，英文条目直接拿来没仔细校对

2，感觉藿烯这个条目应该和胆甾烯，达玛烯一样是个半消歧义条目，这个条目infobox里链接的PubChem和ChEBI页面用的条目名分别是diploptene(绵马三萜)和hop-22(29)-ene，而hopene只是当做Synonyms使用，希望以后有机会移动重建

3，关于菠菜甾醇的CAS，阁下应该是对的，不过菠菜甾醇的pubchem页面[1]的图似乎错了，和维基上的一样，而且也连接到了wikidata的Chondrillasterol（粉苞苣甾醇）页面

--Htmlzycq (talk) 13:05, 22 October 2019 (UTC)[reply]

@Htmlzycq:上述已了解。感谢阁下的回复。--Leiem (talk) 13:17, 22 October 2019 (UTC)[reply]

pubchem和wiki的菠菜甾醇图其实也是对的，和ChemSpider 与 ChEMBL 、 ChEBI的结构图的关系是以23(24)单键旋转了180度而已，是同一个东西。就是pubchem上连接的wikidata链接是错的，谁能去改一下？

ps: 现在感觉wikidata也挺好用的，很多enwiki上搜不到的信息这里能搜到。--Htmlzycq (talk) 15:22, 22 October 2019 (UTC)[reply]

@Htmlzycq:其他网站不太清楚怎么修改。Wikidata确实挺好用的，我现在写条目之前都会在上面找找有没有，有时候可能没有英语版本，但其他语言存在。--Leiem (talk) 15:24, 22 October 2019 (UTC)[reply]

地衣甾醇的图是对的，和[C@H(/C=C/[C@H](C)C(C)C)[C@H]1CC[C@@H]2[C@@]1(CCC3=C2CC=C4[C@@]3(CC[C@@H](C4)O)C)C&zoom=2.0&annotate=cip ]这里的不同在于异丙基一个在上面，一个在右边，这相当于转了180度，实粗线会变虚线。--Htmlzycq (talk) 10:14, 28 October 2019 (UTC)[reply]

霉菌甾醇 516-78-9 的图也没错--Htmlzycq (talk) 10:42, 28 October 2019 (UTC)[reply]

@Htmlzycq:了解。已对相应页面进行更改。--Leiem (talk) 11:07, 28 October 2019 (UTC)[reply]

原来 68515-48-0 这个CAS是几种邻苯二甲酸酯的混合物啊，在下之前还错误地把这个wikidata链接与德语的Diisononylphthalat 这个页面连接起来，那想问一下阁下这个结构对应的CAS号是多少？--Htmlzycq (talk) 13:32, 28 October 2019 (UTC)[reply]

@Htmlzycq:纯异壬酯的CAS是28553-12-0。--Leiem (talk) 13:34, 28 October 2019 (UTC)[reply]

在下问的是“邻苯二甲酸二(3,5,5-三甲基己基)酯”的CAS--Htmlzycq (talk) 13:37, 28 October 2019 (UTC)[reply]

@Htmlzycq:是14103-61-8，已在zhwiki的C₂₆H₄₂O₄内用注释标注。另外，德语Diisononylphthalat的图似乎有问题，条目名称翻译过来是异壬酯（isononyl）。--Leiem (talk) 13:44, 28 October 2019 (UTC)[reply]

参见Q27282495（

）。--Leiem (talk) 13:47, 28 October 2019 (UTC)[reply]

嗯，德语维基上老版本的图可能是对的，现在的图是“邻苯二甲酸二(3,5,5-三甲基己基)酯”（14103-61-8）这个化合物，在下已经放入中文维基邻苯二甲酸酯这个页面的表格里了。--Htmlzycq (talk) 13:51, 28 October 2019 (UTC)[reply]

3-甲基-1-戊醇

看起来589-35-5应该是R/S异构混合的CAS， 20281-83-8和[2]这里查到的 343268-11-1是R/S各自的CAS?

另外，中文维基里的己醇就剩英文里也没有的两个了，阁下不建一下？--Htmlzycq (talk) 06:14, 7 November 2019 (UTC)[reply]

@Htmlzycq:20281-83-8、343268-11-1都属于“被删除的CAS号”（Deleted CAS Registry Numbers），已经不再使用。它们和589-35-5对应同一种物质。剩下的两个我有时间看看。--Leiem (talk) 06:41, 7 November 2019 (UTC)[reply]

原来如此，看起来似乎是589-35-5的R/S两个的各种性质太像了，所以没有人为它们添加各自的CAS号，另外几个在下刚建立的存在手性的仲醇似乎也是这样？--Htmlzycq (talk) 09:38, 7 November 2019 (UTC)[reply]

我明天或者其他时候有时间再查一下。R/S我单独查一下看有没有。--Leiem (talk) 11:27, 7 November 2019 (UTC)[reply]

法语维基百科的己醇页面有各个R/S的CAS，不知道对不对，阁下可以核查一下，我先把没有R/S的给搬到中文维基里来。--Htmlzycq (talk) 12:18, 7 November 2019 (UTC)[reply]

CAS号还真好用啊

阁下之前在中文维基里创建了“氯乙炔”条目，在下用593-63-5这个CAS在wikidata里找到了Q12886113里的两个冷门语言的维基百科链接。

另外，阁下能帮忙看看在下刚搬运到中文维基“C4H4O”里的那个结构图里，除了黑色的CAS号之外，蓝色和绿色各是什么编号吗？--Htmlzycq (talk) 07:02, 6 December 2019 (UTC)[reply]

@Htmlzycq: 不太清楚那两种颜色的编号，可能是Pubchem一类的（？）。顺手查了两个，都有CAS号，绿色21108474的CAS是918826-65-0，名称是(2R)-2-乙炔基环氧乙烷；绿色的21108473的CAS是1127146-16-0，名称(2S)-2-乙炔基环氧乙烷。--Leiem (talk) 07:28, 6 December 2019 (UTC)[reply]

PS: 希腊语有不少“相对冷门”的有机分子条目。--Leiem (talk) 07:30, 6 December 2019 (UTC)[reply]

Translation request

Hello.

Can you translate and upload the article and category en:Postage stamps and postal history of Azerbaijan and en:Category:Postal system of Azerbaijan for that article, and for zh:Azərpoçt and zh:阿塞拜疆邮政编码 in Chinese Wikipedia?

It should not be long.

Yours sincerely, Sarvathi (talk) 19:32, 10 December 2019 (UTC)[reply]

Category creation is done. --Leiem (talk) 06:12, 11 December 2019 (UTC)[reply]

Thank you very much. Sarvathi (talk) 16:29, 11 December 2019 (UTC)[reply]

碳酸丁酯

@Htmlzycq:已经新建单丁酯数据项Q113192054，二丁酯对应的页面的CAS号已经更改。--Leiem (talk) 09:03, 22 July 2022 (UTC)[reply]

为了防止再出现MOLT4的错误链接，在下把NCI-60的中文条目建立了，今天有点忙，还没完工。可以看见里面的中文条目是比英文条目要多的，这要感谢某位维基人--Htmlzycq (talk) 03:29, 26 January 2024 (UTC)[reply]

@Htmlzycq: 那个是我本来以为有条目，就直接链接了，链接完之后发现是重定向。（至于化学式消歧义，只要不是全红应该不会被提删？那些应该可以缓缓）--Leiem (talk) 04:21, 26 January 2024 (UTC)[reply]

二甲基色胺，N，α，数字的排列顺序是什么？--Htmlzycq (talk) 08:51, 14 February 2024 (UTC) 看了三甲基色胺，感觉更乱了--Htmlzycq (talk) 11:05, 14 February 2024 (UTC)[reply]

@Htmlzycq: 看了下《有机化合物命名原则2017》，里面没写这个的顺序，我觉得可以按照英文命名来翻译。--Leiem (talk) 16:15, 14 February 2024 (UTC)[reply]

Recently created chemicals

Hi,

It seems from your contributions that you created some chemicals lately. I fixed things in (-)-Lycoraminone (Q128303911), if you could do the same on the others you created, this would be great. Some of them also seem to already exist and should probably be merged (see the InChIKey warning).

Thank you for contributing to chemistry in Wikidata! AdrianoRutz (talk) 13:47, 6 August 2024 (UTC)[reply]

@AdrianoRutz: I get it, thank you! One question is that (12xi,13xi)-12,13-Epoxy-19-hydroxysenecionan-11,16-dione (Q105182710) and (E)-erucifoline (Q105542710) seem to be same, but they are stereoisomer of (P3364)s according to the statement.--Leiem (talk) 02:15, 7 August 2024 (UTC)[reply]

They are not the same. I now fixed (12xi,13xi)-12,13-Epoxy-19-hydroxysenecionan-11,16-dione (Q105182710) so that hopefully they are not mixed anymore, tell me if anything is left that disturbs you. (I did not change the labels, nor the sitelinks, maybe we should) AdrianoRutz (talk) 04:53, 7 August 2024 (UTC)[reply]

@AdrianoRutz: Thank you. I think if the labels are wrong, they can be changed. Some of my edits are based on CAS register numbers, from SciFinder.--Leiem (talk) 07:45, 8 August 2024 (UTC)[reply]
