2-Benzyl-4-bromo-5-(4-methanesulfonyl-phenyl)-2H-pyridazin-3-one is a complex organic compound with the molecular formula C20H16BrNO4S. It features a pyridazinone core, which is a heterocyclic ring system consisting of a pyridine ring fused to a diazine ring. The compound has a benzyl group attached to the 2-position, a bromine atom at the 4-position, and a 4-methanesulfonyl-phenyl group at the 5-position. The presence of the methanesulfonyl group introduces a sulfonamide functional group, which can potentially enhance the compound's solubility and reactivity. This chemical structure may be of interest in medicinal chemistry and material science due to its potential applications in the development of pharmaceuticals or as a precursor in the synthesis of other complex molecules.

Check Digit Verification of cas no

The CAS Registry Mumber 213764-20-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,3,7,6 and 4 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 213764-20:
(8*2)+(7*1)+(6*3)+(5*7)+(4*6)+(3*4)+(2*2)+(1*0)=116
116 % 10 = 6
So 213764-20-6 is a valid CAS Registry Number.
