Check Digit Verification of cas no

The CAS Registry Mumber 78031-81-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,8,0,3 and 1 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 78031-81:
(7*7)+(6*8)+(5*0)+(4*3)+(3*1)+(2*8)+(1*1)=129
129 % 10 = 9
So 78031-81-9 is a valid CAS Registry Number.
