1072-50-0 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 1072-50-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,0,7 and 2 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1072-50:
(6*1)+(5*0)+(4*7)+(3*2)+(2*5)+(1*0)=50
50 % 10 = 0
So 1072-50-0 is a valid CAS Registry Number.

Acid-Catalyzed Decomposition of 1-Alkyltriazolines: A Mechanistic Study

Smith, Richard H.,Wladkowski, Brian D.,Taylor, Jesse E.,Thompson, Erin J.,Pruski, Brunon,et al.

, p. 2097 - 2103 (1993)

1-Alkyltriazolines are five-membered cyclic triazenes containing the unusual Z-configuration for the triazene moiety.The hydrolytic decomposition of these compounds in aqueous or mixed acetonitrile-aqueous buffers leads predominantly to the formation of the corresponding 1-alkylaziridines and lesser amounts of 2-(alkylamino)ethanols, alkylamines, and acetaldehyde.The latter two products presumably result from hydrolysis of a rearrangement produkt, N-ethylidenealkylamine.Neither the nature of the 1-alkyl group nor the pH of the medium greatly influences the product distribution, although decomposition in purely aqueous buffers slightly reduces the aziridine yields.The rate of hydrolysis of 1-alkyltriazolines is about twice as fast as that of the analogous acyclic 1,3,3-trialkyltriazenes and varies in the order tert-butyl > isopropyl > ethyl > butyl > methyl > propyl > benzyl.The mechanism of the decomposition is specific acid-catalyzed (A1) involving rapid reversible protonation followed by rate-limiting formation of a 2-(alkylamino)ethyldiazonium ion.The slopes of the log kobs versus pH plots are near -1.0.The solvent deuterium isotope effect, kH2O/kD2O, is in all cases methyl > ethyl.
