Check Digit Verification of cas no

The CAS Registry Mumber 119820-60-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,9,8,2 and 0 respectively; the second part has 2 digits, 6 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 119820-60:
(8*1)+(7*1)+(6*9)+(5*8)+(4*2)+(3*0)+(2*6)+(1*0)=129
129 % 10 = 9
So 119820-60-9 is a valid CAS Registry Number.
