The record was created by an explicit CAS-to-ChEBI lookup and its current CAS RN 25322-68-3 uniquely resolves by ChEBI xref to CHEBI:46793 'poly(ethylene glycol)'. CAS_RN_LOOKUP records the method that established this mapping; a lexical grade would discard that provenance. ontology_id is unchanged. The own-identifier SSSOM predicate remains skos:exactMatch under Rule D (#438), independently of mapping quality. | |
