Check Digit Verification of cas no
The CAS Registry Mumber 437761-09-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,3,7,7,6 and 1 respectively; the second part has 2 digits, 0 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 437761-09:
(8*4)+(7*3)+(6*7)+(5*7)+(4*6)+(3*1)+(2*0)+(1*9)=166
166 % 10 = 6
So 437761-09-6 is a valid CAS Registry Number.

Design and synthesis of bicyclic pyrimidinone-based HCV NS3 protease inhibitors
Glunz, Peter W.,Douty, Brent D.,Decicco, Carl P.
, p. 785 - 788 (2007/10/03)
A series of bicyclic pyrimidinone-based HCV NS3 protease inhibitors was synthesized via selective C8 position functionalization. Substituted phenylamides and phenylureas were preferred in the S2 binding pocket.
