Check Digit Verification of cas no

The CAS Registry Mumber 90909-66-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,0,9,0 and 9 respectively; the second part has 2 digits, 6 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 90909-66:
(7*9)+(6*0)+(5*9)+(4*0)+(3*9)+(2*6)+(1*6)=153
153 % 10 = 3
So 90909-66-3 is a valid CAS Registry Number.
