Missing InChI=Edit

benzene (Q2270) currently lists InChI (P234) as "1S/C6H6/c1-2-4-6-5-3-1/h1-6H". This seems to be missing the "InChI=" part. Justification:

Personally I don't yet have enough experience with InChI to judge whether embedding the name of the identifier in the identifier is a good thing. But for interoperability I propose that Wikidata follows the common scheme and adds the InChI= prefix. Toni 001 (talk) 15:40, 6 September 2019 (UTC)
