Check Digit Verification of cas no

The CAS Registry Mumber 1276118-81-0 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,7,6,1,1 and 8 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1276118-81:
(9*1)+(8*2)+(7*7)+(6*6)+(5*1)+(4*1)+(3*8)+(2*8)+(1*1)=160
160 % 10 = 0
So 1276118-81-0 is a valid CAS Registry Number.
