The record's label does not equal the term's primary label 'alantolactone'; it matches the ChEBI synonym 'Helenine' on CHEBI:2540. The schema defines EXACT_MATCH as a direct match to the term and SYNONYM_MATCH as a match to a known synonym, so the recorded grade overstated. ontology_id is unchanged — the term is correct. The SSSOM predicate is unaffected (both grades emit skos:exactMatch). | |

The record was created by an explicit CAS-to-ChEBI lookup and its current CAS RN 546-43-0 uniquely resolves by ChEBI xref to CHEBI:2540 'alantolactone'. 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. |
