Check Digit Verification of cas no

The CAS Registry Mumber 134940-39-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,4,9,4 and 0 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 134940-39:
(8*1)+(7*3)+(6*4)+(5*9)+(4*4)+(3*0)+(2*3)+(1*9)=129
129 % 10 = 9
