Check Digit Verification of cas no

The CAS Registry Mumber 219625-03-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,9,6,2 and 5 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 219625-03:
(8*2)+(7*1)+(6*9)+(5*6)+(4*2)+(3*5)+(2*0)+(1*3)=133
133 % 10 = 3
So 219625-03-3 is a valid CAS Registry Number.

Synthesis and structure-activity relationship (SAR) studies of L-cysteine-based N-type calcium channel blockers are described. In the course of exploring SAR of the N- and C-terminal substituents, the L-cysteine derivative was found to be a potent N-type calcium channel blocker with an IC(50) value of 0.14 microM on IMR-32 assay. Compound showed 12-fold selectivity for N-type over L-type calcium channels on AtT-20 assay.
