Check Digit Verification of cas no

The CAS Registry Mumber 4999-69-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,9,9 and 9 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 4999-69:
(6*4)+(5*9)+(4*9)+(3*9)+(2*6)+(1*9)=153
153 % 10 = 3
So 4999-69-3 is a valid CAS Registry Number.
