Evidence (2)

DATABASE_MATCH via CultureBotHT

SUPERSEDED (#456): the CAS-selected ChEBI term denotes a different stereochemical form. Original note follows. Imported from CultureBotHT. CAS-RN→CHEBI mapping resolved via OAK CHEBI sqlite (cas xref).

CURATOR_JUDGMENT via MIM curation (#456)

The CultureBotHT label and CAS-RN name a racemate, while CHEBI:139272 is stereo-unspecified and has separate R and S children. No exact local ChEBI term denotes the racemate. Per MAPPING_SEMANTICS.md Section 3, the record now uses cas:10237-77-1 as the exact registry identity plus a narrowMatch to CHEBI:139272.
