274918-52-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 274918-52-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,7,4,9,1 and 8 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 274918-52:
(8*2)+(7*7)+(6*4)+(5*9)+(4*1)+(3*8)+(2*5)+(1*2)=174
174 % 10 = 4
So 274918-52-4 is a valid CAS Registry Number.

α-Ketoamides, α-ketoesters and α-diketones as HCV NS3 protease inhibitors
Han, Wei,Hu, Zilun,Jiang, Xiangjun,Decicco, Carl P.
, p. 711 - 713 (2000)
Peptide-based α-ketoamides, α-ketoesters and α-diketones were designed, synthesized and evaluated against HCV NS3 protease. α-Ketoamides have the highest affinity among the three classes, with 8 being the most potent inhibitor with an IC50 of 3
