Check Digit Verification of cas no

The CAS Registry Mumber 4254-45-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,2,5 and 4 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 4254-45:
(6*4)+(5*2)+(4*5)+(3*4)+(2*4)+(1*5)=79
79 % 10 = 9
So 4254-45-9 is a valid CAS Registry Number.
