Check Digit Verification of cas no

The CAS Registry Mumber 108140-13-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,8,1,4 and 0 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 108140-13:
(8*1)+(7*0)+(6*8)+(5*1)+(4*4)+(3*0)+(2*1)+(1*3)=82
