Check Digit Verification of cas no

The CAS Registry Mumber 1201685-85-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,0,1,6,8 and 5 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1201685-85:
(9*1)+(8*2)+(7*0)+(6*1)+(5*6)+(4*8)+(3*5)+(2*8)+(1*5)=129
129 % 10 = 9
So 1201685-85-9 is a valid CAS Registry Number.
