Check Digit Verification of cas no

The CAS Registry Mumber 109508-84-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,9,5,0 and 8 respectively; the second part has 2 digits, 8 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 109508-84:
(8*1)+(7*0)+(6*9)+(5*5)+(4*0)+(3*8)+(2*8)+(1*4)=131
