Check Digit Verification of cas no

The CAS Registry Mumber 63815-38-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,3,8,1 and 5 respectively; the second part has 2 digits, 3 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 63815-38:
(7*6)+(6*3)+(5*8)+(4*1)+(3*5)+(2*3)+(1*8)=133
133 % 10 = 3
So 63815-38-3 is a valid CAS Registry Number.
