Check Digit Verification of cas no

The CAS Registry Mumber 139333-20-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,9,3,3 and 3 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 139333-20:
(8*1)+(7*3)+(6*9)+(5*3)+(4*3)+(3*3)+(2*2)+(1*0)=123
123 % 10 = 3
So 139333-20-3 is a valid CAS Registry Number.
