Check Digit Verification of cas no

The CAS Registry Mumber 56562-66-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,6,5,6 and 2 respectively; the second part has 2 digits, 6 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 56562-66:
(7*5)+(6*6)+(5*5)+(4*6)+(3*2)+(2*6)+(1*6)=144
144 % 10 = 4
So 56562-66-4 is a valid CAS Registry Number.
