Check Digit Verification of cas no

The CAS Registry Mumber 99475-11-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,9,4,7 and 5 respectively; the second part has 2 digits, 1 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 99475-11:
(7*9)+(6*9)+(5*4)+(4*7)+(3*5)+(2*1)+(1*1)=183
183 % 10 = 3
So 99475-11-3 is a valid CAS Registry Number.
