Check Digit Verification of cas no

The CAS Registry Mumber 4457-26-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,4,5 and 7 respectively; the second part has 2 digits, 2 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 4457-26:
(6*4)+(5*4)+(4*5)+(3*7)+(2*2)+(1*6)=95
95 % 10 = 5
So 4457-26-5 is a valid CAS Registry Number.
