Check Digit Verification of cas no

The CAS Registry Mumber 4440-05-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,4,4 and 0 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 4440-05:
(6*4)+(5*4)+(4*4)+(3*0)+(2*0)+(1*5)=65
65 % 10 = 5
So 4440-05-5 is a valid CAS Registry Number.
