The CAS Registry Mumber 2538-84-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,5,3 and 8 respectively; the second part has 2 digits, 8 and 4 respectively.Calculate Digit Verification of CAS Registry Number 2538-84:
(6*2)+(5*5)+(4*3)+(3*8)+(2*8)+(1*4)=93
93 % 10 = 3
So 2538-84-3 is a valid CAS Registry Number.
