Check Digit Verification of cas no
The CAS Registry Mumber 802034-95-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,0,2,0,3 and 4 respectively; the second part has 2 digits, 9 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 802034-95:
(8*8)+(7*0)+(6*2)+(5*0)+(4*3)+(3*4)+(2*9)+(1*5)=123
123 % 10 = 3
So 802034-95-3 is a valid CAS Registry Number.

A series of azaheterocyclic carbazole sulfonamides was synthesized and evaluated for antiproliferative activity. The most potent compounds N-(2,6-dimethoxypyridine-3-yl)-9-ethyl and 9-methylcarbazole-3-sulfonamide (13 and 14) gave significant cytotoxicity (IC50 = 122 and 101 nM). Compound 13 displayed submicromolar activities against seven human tumor cell lines. The SARs of this series of sulfonamides which includes the influence of azaheterocycle rings, sulfonamide linkage, and the carbazole ring are described.
