The CAS Registry Mumber 28456-18-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,8,4,5 and 6 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 28456-18:
(7*2)+(6*8)+(5*4)+(4*5)+(3*6)+(2*1)+(1*8)=130
130 % 10 = 0
So 28456-18-0 is a valid CAS Registry Number.
