Check Digit Verification of cas no

The CAS Registry Mumber 133475-75-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,3,4,7 and 5 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 133475-75:
(8*1)+(7*3)+(6*3)+(5*4)+(4*7)+(3*5)+(2*7)+(1*5)=129
129 % 10 = 9
So 133475-75-9 is a valid CAS Registry Number.
