This structure doesn't display properly (all atoms overlapped). The CAS number associated with this record is already associated with two other records http://www.chemspider.com/Chemical-Structure.24772514.html and http://www.chemspider.com/Chemical-Structure.65749.html As far as I can see, those two are essentially equivalent (only tautomer / aromatic resonance differences). The SMILES for this record gives me the same structure as 24772514.

The structure has now been tidied, The structures that you highlight are tautomers - these records reflect the limitations of the InChI's tautomer handling.
