Check Digit Verification of cas no

The CAS Registry Mumber 1217649-53-0 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,1,7,6,4 and 9 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1217649-53:
(9*1)+(8*2)+(7*1)+(6*7)+(5*6)+(4*4)+(3*9)+(2*5)+(1*3)=160
160 % 10 = 0
So 1217649-53-0 is a valid CAS Registry Number.

Synthesis of new thienyl ring containing HIV-1 protease inhibitors: Promising preliminary pharmacological evaluation against recombinant HIV-1 proteases

supporting information; experimental part, p. 1451 - 1457 (2010/07/05)

A series of new thienyl ring containing analogues of nelfinavir and saquinavir with different, substitution patterns were synthesized from suitable enantiopure diols. Their inhibitory activity against wild type recombinant HIV-1 protease was evaluated. In general thienyl groups spaced from the core by a methylene group gave products showing IC50 in the nanomolar range, irrespective of the type and the substitution pattern of the heterocycle. The range of activity of the two most, active compounds is substantially maintained or even increased against two commonly selected mutants, under drug pressure, such as V32I and V82A.
