90833-49-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 90833-49-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,0,8,3 and 3 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 90833-49:
(7*9)+(6*0)+(5*8)+(4*3)+(3*3)+(2*4)+(1*9)=141
141 % 10 = 1
So 90833-49-1 is a valid CAS Registry Number.

Structure-activity relationship (SAR) studies of quinoxalines as novel HCV NS5B RNA-dependent RNA polymerase inhibitors

Rong, Frank,Chow, Suetying,Yan, Shunqi,Larson, Gary,Hong, Zhi,Wu, Jim

, p. 1663 - 1666 (2007)

From chemical compound library screening using an HCV NS5B RNA-dependent RNA polymerase enzymatic assay, we identified a substituted quinoxaline hit with an IC50 of 5.5 μM. A series of substituted quinoxaline amide derivatives were synthesized
