Check Digit Verification of cas no

The CAS Registry Mumber 133409-91-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,3,4,0 and 9 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 133409-91:
(8*1)+(7*3)+(6*3)+(5*4)+(4*0)+(3*9)+(2*9)+(1*1)=113
113 % 10 = 3
So 133409-91-3 is a valid CAS Registry Number.
