Check Digit Verification of cas no

The CAS Registry Mumber 136920-13-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,6,9,2 and 0 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 136920-13:
(8*1)+(7*3)+(6*6)+(5*9)+(4*2)+(3*0)+(2*1)+(1*3)=123
123 % 10 = 3
So 136920-13-3 is a valid CAS Registry Number.
