| 2026-08-06T00:00:00+00:00 | issue_114_cas_audit LLM | CORRECTED | cas_rn 200-416-4 -> 26566-61-0. 200-416-4 is an EC/EINECS registry number (format NNN-NNN-N), not a CAS-RN — the same class of fetch_cas_rn_from_pubchem mis-assignment as Beef extract's 103-47-9 (=CHES) in #114. The replacement is this record's own CHEBI term CHEBI:28260's CAS dbxref, and that term's label matches the substance, so it is evidence rather than inference. The EC number is recorded here rather than discarded: it was correct information in the wrong field. | |
