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.

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). |
