4',5',6'-Trihydroxy-3'-benzolsulfonyl-6,7-benzo-tropolon is a complex organic compound characterized by its unique molecular structure. It features a tropolone core, which is a type of aromatic compound with a seven-membered ring containing three double bonds and a ketone group. The molecule is further distinguished by the presence of three hydroxyl groups at the 4', 5', and 6' positions, and a benzenesulfonyl group attached at the 3' position. This benzenesulfonyl group is a sulfonate ester derived from benzene, which adds to the compound's complexity and potential reactivity. The compound's structure and properties make it a subject of interest in organic chemistry, potentially for its applications in the synthesis of pharmaceuticals or other specialty chemicals.

Check Digit Verification of cas no

The CAS Registry Mumber 3997-57-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,9,9 and 7 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 3997-57:
(6*3)+(5*9)+(4*9)+(3*7)+(2*5)+(1*7)=137
137 % 10 = 7
So 3997-57-7 is a valid CAS Registry Number.
