Check Digit Verification of cas no

The CAS Registry Mumber 113982-20-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,3,9,8 and 2 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 113982-20:
(8*1)+(7*1)+(6*3)+(5*9)+(4*8)+(3*2)+(2*2)+(1*0)=120
120 % 10 = 0
So 113982-20-0 is a valid CAS Registry Number.
