Check Digit Verification of cas no

The CAS Registry Mumber 1575-13-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,5,7 and 5 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1575-13:
(6*1)+(5*5)+(4*7)+(3*5)+(2*1)+(1*3)=79
79 % 10 = 9
So 1575-13-9 is a valid CAS Registry Number.
