Check Digit Verification of cas no

The CAS Registry Mumber 62083-32-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,2,0,8 and 3 respectively; the second part has 2 digits, 3 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 62083-32:
(7*6)+(6*2)+(5*0)+(4*8)+(3*3)+(2*3)+(1*2)=103
103 % 10 = 3
So 62083-32-3 is a valid CAS Registry Number.
