DATABASE_MATCH via CultureBotHT

Imported from CultureBotHT. CAS-RN 157574-76-0 present, but no CHEBI entry exists (checked OAK CHEBI sqlite + PubChem CID synonyms). Curator can promote to a CHEBI primary if/when CHEBI adds the term.

DATABASE_MATCH via CHEBI via OLS (stem-substring)

SUPERSEDED (#312): Parent class identified via stem-substring; matched_via="6'-O-sialyllactose sodium salt"

MANUAL_CURATION via MIM curation (#312); chebi.db

parent CHEBI:26714 ('sodium salt') -> CHEBI:153372 ('5-acetamido-3,5-dideoxy-D-glycero-alpha-D-galacto-non-2-ulopyranonosyl-(2->6)-beta-D-galactopyranosyl-(1->4)-D-glucopyranose'). As for the 3'-isomer: CHEBI:26714 is the class of sodium salts. The label names 6'-sialyllactose, and CHEBI:153372 carries the related synonyms "6'-sialyllactose" and "6'SL"; it is the anomer-unspecified D-glucopyranose form, so it is the closest broader term for the salt. cas:157574-76-0 identity, NARROW_MATCH grade and both registry rows unchanged (Section 3 step 2, #245).
