Check Digit Verification of cas no

The CAS Registry Mumber 4582-66-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,5,8 and 2 respectively; the second part has 2 digits, 6 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 4582-66:
(6*4)+(5*5)+(4*8)+(3*2)+(2*6)+(1*6)=105
105 % 10 = 5
So 4582-66-5 is a valid CAS Registry Number.
