Check Digit Verification of cas no

The CAS Registry Mumber 1281027-29-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,8,1,0,2 and 7 respectively; the second part has 2 digits, 2 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1281027-29:
(9*1)+(8*2)+(7*8)+(6*1)+(5*0)+(4*2)+(3*7)+(2*2)+(1*9)=129
129 % 10 = 9
So 1281027-29-9 is a valid CAS Registry Number.
