Check Digit Verification of cas no

The CAS Registry Mumber 80815-13-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,0,8,1 and 5 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 80815-13:
(7*8)+(6*0)+(5*8)+(4*1)+(3*5)+(2*1)+(1*3)=120
120 % 10 = 0
So 80815-13-0 is a valid CAS Registry Number.
