Check Digit Verification of cas no

The CAS Registry Mumber 13311-52-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,3,3,1 and 1 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 13311-52:
(7*1)+(6*3)+(5*3)+(4*1)+(3*1)+(2*5)+(1*2)=59
59 % 10 = 9
So 13311-52-9 is a valid CAS Registry Number.
