Check Digit Verification of cas no

The CAS Registry Mumber 74991-80-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,4,9,9 and 1 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 74991-80:
(7*7)+(6*4)+(5*9)+(4*9)+(3*1)+(2*8)+(1*0)=173
173 % 10 = 3
So 74991-80-3 is a valid CAS Registry Number.
