Check Digit Verification of cas no

The CAS Registry Mumber 908131-20-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,0,8,1,3 and 1 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 908131-20:
(8*9)+(7*0)+(6*8)+(5*1)+(4*3)+(3*1)+(2*2)+(1*0)=144
144 % 10 = 4
So 908131-20-4 is a valid CAS Registry Number.
