Check Digit Verification of cas no
The CAS Registry Mumber 28752-68-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,8,7,5 and 2 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 28752-68:
(7*2)+(6*8)+(5*7)+(4*5)+(3*2)+(2*6)+(1*8)=143
143 % 10 = 3
So 28752-68-3 is a valid CAS Registry Number.

Aminopyrine and Antipyrine Free Radical-cations: Pulse Radiolysis Studies of One-electron Transfer Reactions
Forni, Luigi G.,Mora-Arellano, Victor O.,Packer, John E.,Willson, Robin L.
, p. 1579 - 1584 (2007/10/02)
Absolute rate constants for the reaction of a variety of electrophilic free radicals with the pyrazoline derivatives aminopyrine and antipyrine have been measured by pulse radiolysis.In the case of aminopyrine the resulting radical cation is a particularly stable species ε325 5.35*103 dm3 mol-1 cm-1).Both compounds are readily oxidised to their respective radical-cations with the one-electron oxidation potential of antipyrine (E0 1.1-1.6 V) being higher than that of aminopyrine (E0 0.26-0.5 V).Studies of the reaction of the radical-cations with reducing agents suggest that aminopyrine in particular may prove to be a useful reference compound in studies of free radical one-electron oxidations.
