Check Digit Verification of cas no

The CAS Registry Mumber 133071-01-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,3,0,7 and 1 respectively; the second part has 2 digits, 0 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 133071-01:
(8*1)+(7*3)+(6*3)+(5*0)+(4*7)+(3*1)+(2*0)+(1*1)=79
79 % 10 = 9
So 133071-01-9 is a valid CAS Registry Number.
