Calculate Digit Verification of CAS Registry Number 34000-44:
(7*3)+(6*4)+(5*0)+(4*0)+(3*0)+(2*4)+(1*4)=57
57 % 10 = 7
So 34000-44-7 is a valid CAS Registry Number.

Investigations on the stability of l-methyl-2-phenylacetohydrazide

Bresser,Weber

, p. 470 - 476 (2007/10/03)

l-Methyl-2-phenylacetohydrazide (1), a degradation product of dipyrone, is hydrolytically stable. In contrast it is oxidized into several products like 3a/3b, 4 and 5a/5b. The composition of the reaction mixture depends on the oxidation conditions (ferricyanide; hydrogenperoxide with/without peroxidase; pH 5-9) and was determined by capillary column gaschromatography.
