Check Digit Verification of cas no

The CAS Registry Mumber 4991-69-9 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 1 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 4991-69:
(6*4)+(5*9)+(4*9)+(3*1)+(2*6)+(1*9)=129
129 % 10 = 9
So 4991-69-9 is a valid CAS Registry Number.
