Check Digit Verification of cas no

The CAS Registry Mumber 34880-80-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,4,8,8 and 0 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 34880-80:
(7*3)+(6*4)+(5*8)+(4*8)+(3*0)+(2*8)+(1*0)=133
133 % 10 = 3
So 34880-80-3 is a valid CAS Registry Number.
