Check Digit Verification of cas no

The CAS Registry Mumber 1286261-21-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,8,6,2,6 and 1 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1286261-21:
(9*1)+(8*2)+(7*8)+(6*6)+(5*2)+(4*6)+(3*1)+(2*2)+(1*1)=159
