Check Digit Verification of cas no

The CAS Registry Mumber 99469-85-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,9,4,6 and 9 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 99469-85:
(7*9)+(6*9)+(5*4)+(4*6)+(3*9)+(2*8)+(1*5)=209
209 % 10 = 9
So 99469-85-9 is a valid CAS Registry Number.
