Check Digit Verification of cas no

The CAS Registry Mumber 743434-65-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 7,4,3,4,3 and 4 respectively; the second part has 2 digits, 6 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 743434-65:
(8*7)+(7*4)+(6*3)+(5*4)+(4*3)+(3*4)+(2*6)+(1*5)=163
163 % 10 = 3
So 743434-65-3 is a valid CAS Registry Number.
