Check Digit Verification of cas no

The CAS Registry Mumber 133348-31-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,3,3,4 and 8 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 133348-31:
(8*1)+(7*3)+(6*3)+(5*3)+(4*4)+(3*8)+(2*3)+(1*1)=109
109 % 10 = 9
So 133348-31-9 is a valid CAS Registry Number.
