Check Digit Verification of cas no

The CAS Registry Mumber 4224-80-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,2,2 and 4 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 4224-80:
(6*4)+(5*2)+(4*2)+(3*4)+(2*8)+(1*0)=70
70 % 10 = 0
So 4224-80-0 is a valid CAS Registry Number.
