Check Digit Verification of cas no

The CAS Registry Mumber 1334145-71-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,3,4,1,4 and 5 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1334145-71:
(9*1)+(8*3)+(7*3)+(6*4)+(5*1)+(4*4)+(3*5)+(2*7)+(1*1)=129
129 % 10 = 9
