Check Digit Verification of cas no

The CAS Registry Mumber 74642-16-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,4,6,4 and 2 respectively; the second part has 2 digits, 1 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 74642-16:
(7*7)+(6*4)+(5*6)+(4*4)+(3*2)+(2*1)+(1*6)=133
133 % 10 = 3
So 74642-16-3 is a valid CAS Registry Number.
