Check Digit Verification of cas no

The CAS Registry Mumber 113326-71-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,3,3,2 and 6 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 113326-71:
(8*1)+(7*1)+(6*3)+(5*3)+(4*2)+(3*6)+(2*7)+(1*1)=89
89 % 10 = 9
So 113326-71-9 is a valid CAS Registry Number.
