Topic on User talk:SCIdude

Dear SCIdude, you created a lot of new items recently especially about chemicals but some of those chemicals already have an item. Please check and merge if necessary. You can use the constraint violation reports to identify the problem. See new InChIKey constraint violation to identify the chemicals with a problem. I can only recommend you to check the existence of chemical using identifier and not using label to be sure that a new item is necessary, for example by checking if an InChIKey is not already present in an item. You can use that tool to preform that task. Thank you. Snipre (talk) 10:04, 17 November 2019 (UTC)

You should know that zwitterions have the same key---apart from that...not sure why this happened, I checked keys beforehand. But hey, only 28, that's nothing.

28 were identified using InChIKey, but there are a lot of chemicals items without InChIkey, so the potential for larger number than 28 exist. If you want you can check other constraint violation reports:

I did not add any of the other IDs so I'll ignore this.
