Merged because differs from the winning record only in the case of its first letter, and was grounded to the alpha anomer while the winner holds the anomer-agnostic term its CAS 69-79-4 points at. The CAS-vs-CURIE conflict #320 flagged on that record was a symptom of the duplicate, not of a bad mapping. Occurrences 139/58 + 2/2 -> 141/60. Raw label kept as a RAW_TEXT synonym. | |
