Link to databaseEdit

Why is the ID not linked to the database? In Q130336 for example only PubChem ID is linked, but not the ChemSpider ID. --Leyo 08:55, 23 July 2013 (UTC)

Hi Leyo! I think I just forgot to link it at MediaWiki talk:Gadget-AuthorityControl.js. I'm going to fix it. --Tobias1984 (talk) 09:01, 23 July 2013 (UTC)

Reasons for exception to single value constraintEdit

I have cleared exceptions to the single value constraints. Most of them had two ChemSpider IDs, one correct and one with incorrect data (sometimes ChemSpider entries have the same data like InChI/InChIKey/systematic name/SMILES/structure, but non-standard InChI is different and suggests that the compound have in fact other configuration etc.). Below I started a list of known and confirmed situations in which two ChemSpider IDs should point to one Wikidata entry. Wostr (talk) 23:52, 10 December 2019 (UTC)

List of exceptions to single value constraint:

  • ChemSpider distinguishes 'compound with explicitly undefined stereocenter' and 'compound with unknown stereocenter'; the only difference in these entries may be the structure (wiggly bond vs plain bond) and/or non-standard InChI (which is not visible to readers without signing in and clicking on the "Wikibox" link):
