Check Digit Verification of cas no

The CAS Registry Mumber 445220-55-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,4,5,2,2 and 0 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 445220-55:
(8*4)+(7*4)+(6*5)+(5*2)+(4*2)+(3*0)+(2*5)+(1*5)=123
123 % 10 = 3
So 445220-55-3 is a valid CAS Registry Number.
