PubChem is an aggregator database. It does not, and never has, curated the
structure records, which are all provided by external data depositors.

In case of cemadotin, there are 6 depositors which all sent the same
structure, and presumably still have the same data in their original
databases: LeadScope, NextBio, NovoSeek, ChemIDPlus, ABIChem, and,
ironically, ChemSpider (the guys who are always quick to claim that their
structures are superior because they curate - sometimes). Fixing the record
in PubChem would not achieve anything. Links to those 6 data depositors can
be found on the SID section of the PubChem detail page. After they have
fixed their original data, this will be tracked by PubChem.
