Check Digit Verification of cas no

The CAS Registry Mumber 5317-91-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,3,1 and 7 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 5317-91:
(6*5)+(5*3)+(4*1)+(3*7)+(2*9)+(1*1)=89
89 % 10 = 9
So 5317-91-9 is a valid CAS Registry Number.

, p. 1751 - 1755 (2007/10/03)

A series of chain-branched 1,3-dibenzylthiourea derivatives were synthesized, and tested their antagonist activity against vanilloid receptor 1. Chain-branching led to a significant change in the mode of action and the potency. (R)-Methyl or ethyl-branched 1,3-dibenzylthiourea derivatives showed the most potent antagonist activity up to the IC50 value of 0.05 μM which is 10-fold more potent than capsazepine.
