Check Digit Verification of cas no

The CAS Registry Mumber 112641-29-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,2,6,4 and 1 respectively; the second part has 2 digits, 2 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 112641-29:
(8*1)+(7*1)+(6*2)+(5*6)+(4*4)+(3*1)+(2*2)+(1*9)=89
89 % 10 = 9
So 112641-29-9 is a valid CAS Registry Number.
