Check Digit Verification of cas no

The CAS Registry Mumber 81850-31-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,1,8,5 and 0 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 81850-31:
(7*8)+(6*1)+(5*8)+(4*5)+(3*0)+(2*3)+(1*1)=129
129 % 10 = 9
So 81850-31-9 is a valid CAS Registry Number.
