Check Digit Verification of cas no

The CAS Registry Mumber 5328-03-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,3,2 and 8 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 5328-03:
(6*5)+(5*3)+(4*2)+(3*8)+(2*0)+(1*3)=80
80 % 10 = 0
So 5328-03-0 is a valid CAS Registry Number.
