Date Severity Status Feedback
Dec 10 2012 7:42AM Normal Acknowledged a search for CAS 149979-41-9 produces this record and 2 others, the second is a tautomeric version of this structure, it is THIS record (11677300) which should be preferred. The third record needs sorting out !
Although this tautomer is preferred, since both this and the second record are valid structures and are supported by the data sources I have left the RN against both. Both will come up on a search of that RN, and since this record has the most data sources it will probably see the most use. I've removed the incorrect RN from the third record.
