The CAS Registry Mumber 820-00-8 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 8,2 and 0 respectively; the second part has 2 digits, 0 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 820-00:
(5*8)+(4*2)+(3*0)+(2*0)+(1*0)=48
48 % 10 = 8
So 820-00-8 is a valid CAS Registry Number.
