A CAS Registry Number never carries leading zeros, so the padded form resolved against nothing and any join on CAS-RN silently missed this record. The stripped value passes the CAS check digit and resolves on PubChem to exactly this compound; the padding was ingest alignment, not identity. | |
| 2026-09-23T04:49:29.777562+00:00 | claude LLM | MERGED_INTO | REJECTED | Merged into CHEBI:35697 'trans-Cinnamic acid'; occurrences transferred. Tombstoned REJECTED, SSSOM rows dropped. The record's only source-supplied identity is CAS 140-10-3, which ChEBI xrefs on CHEBI:35697 trans-cinnamic acid only; the geometry-unspecified CHEBI:27386's sole CAS is 621-82-9. MAPPING_SEMANTICS Section 3 step 4's evidence hatch picks the trans isomer, already held by this record (#312). |

The record's only source-supplied identity is CAS 140-10-3 (CultureBotHT), which ChEBI xrefs on CHEBI:35697 trans-cinnamic acid only; the geometry-unspecified CHEBI:27386's sole CAS is 621-82-9. Section 3 step 4's evidence hatch picks the trans isomer, which Trans-cinnamic_Acid already holds, so the two records denote one substance (#312). |
