Check Digit Verification of cas no

The CAS Registry Mumber 4332-44-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,3,3 and 2 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 4332-44:
(6*4)+(5*3)+(4*3)+(3*2)+(2*4)+(1*4)=69
69 % 10 = 9
So 4332-44-9 is a valid CAS Registry Number.
