Check Digit Verification of cas no

The CAS Registry Mumber 41440-05-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,1,4,4 and 0 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 41440-05:
75 % 10 = 5
So 41440-05-5 is a valid CAS Registry Number.
