Check Digit Verification of cas no

The CAS Registry Mumber 1173898-55-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,7,3,8,9 and 8 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1173898-55:
(9*1)+(8*1)+(7*7)+(6*3)+(5*8)+(4*9)+(3*8)+(2*5)+(1*5)=199
199 % 10 = 9
So 1173898-55-9 is a valid CAS Registry Number.

Modification of 1,3,3,4-tetra-substituted pyrrolidine embodied CCR5 receptor antagonists revealed that introducing a fluoro group at the 3-position of the 3-phenyl group to reduce metabolism did not adversely affect the high potency against HIV infection, and that replacing the piperidine ring with a tropane ring could deliver the most potent anti-HIV agents. Stereochemistry of the substituted tropane ring is essential for maintaining the potent anti-HIV activity because only exo-isomers displayed subnanomolar whole cell activity.
