The CAS Registry Mumber 80357-26-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,0,3,5 and 7 respectively; the second part has 2 digits, 2 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 80357-26:
(7*8)+(6*0)+(5*3)+(4*5)+(3*7)+(2*2)+(1*6)=122
122 % 10 = 2

Preparation and Antiinflammatory Activity of 2- and 4-Pyridones

Pierce, James Benjamin,Ariyan, Zaven S.,Ovenden, Gaye Stuart

, p. 131 - 136 (2007/10/02)

Several N-alkyl- and N-arylacetoamides have been self-condensed to form pyridones.N-Alkylacetoacetamides give 2-pyridones, while N-arylacetoamides give 4-pyridones.In an attempt to develop nonacidic, nonsteroidal antiinflammatory agents, the pyridones were tested in a carrageenan-induced pedal edema assay in rats.While the 2-pyridones were not active, 9 of 17 4-pyridones tested were active, and one compound (4g) had antiinflammatory efficacy in a dose-response assay (ED50 values).Most compounds were considered nontoxic by determination of approximate LD50 values in mice by a standard multidimensional observational assay.
