Check Digit Verification of cas no

The CAS Registry Mumber 115276-56-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,5,2,7 and 6 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 115276-56:
(8*1)+(7*1)+(6*5)+(5*2)+(4*7)+(3*6)+(2*5)+(1*6)=117
117 % 10 = 7
So 115276-56-7 is a valid CAS Registry Number.

, p. 108 - 114 (2012)

Boceprevir is a hepatitis C virus (HCV) NS3 protease inhibitor for HCV treatment. [14C]Boceprevir (SCH 503034, trade name Victrelis) was synthesized from K14CN in 11 steps with an overall yield of 16.4%. [13C3]Boceprevir was synthesized in 16 steps with a 2.5% overall yield. The carbon-13 in the molecule was distributed along the peptide chain. [D9]Boceprevir was synthesized from [D9]-t- butylamine in four steps with an overall yield of 69%.
