Check Digit Verification of cas no

The CAS Registry Mumber 13169-73-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,3,1,6 and 9 respectively; the second part has 2 digits, 7 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 13169-73:
(7*1)+(6*3)+(5*1)+(4*6)+(3*9)+(2*7)+(1*3)=98
98 % 10 = 8
So 13169-73-8 is a valid CAS Registry Number.
