Check Digit Verification of cas no

The CAS Registry Mumber 4320-55-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,3,2 and 0 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 4320-55:
(6*4)+(5*3)+(4*2)+(3*0)+(2*5)+(1*5)=62
62 % 10 = 2
So 4320-55-2 is a valid CAS Registry Number.
