Notclassified
Check Digit Verification of cas no
The CAS Registry Mumber 10431-98-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,0,4,3 and 1 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 10431-98:
(7*1)+(6*0)+(5*4)+(4*3)+(3*1)+(2*9)+(1*8)=68
68 % 10 = 8
So 10431-98-8 is a valid CAS Registry Number.

Synthesis of 2-oxazolines via boron esters of N-(2-hydroxyethyl) amides
Ilkgul, Baris,Gunes, Deniz,Sirkecioglu, Okan,Bicak, Niyazi
, p. 5313 - 5315 (2010)
A new, convenient, one-pot process is presented for the synthesis of 2-oxazolines in high yields (75-94%) via boron esters of N-(2-hydroxyethyl) amides. The procedure involves thermolysis of the boron esters at 240-260 °C, in the presence of solid CaO as an acid scavenger and allows the preparation of oxazolines from hydroxyethyl amides of aliphatic and aromatic monocarboxylic acids.
CuCl-catalyzed radical cyclisation of N-α-perchloroacyl-ketene-N,S- acetals: A new way to prepare disubstituted maleic anhydrides
Cornia, Andrea,Felluga, Fulvia,Frenna, Vincenzo,Ghelfi, Franco,Parsons, Andrew F.,Pattarozzi, Mariella,Roncaglia, Fabrizio,Spinelli, Domenico
experimental part, p. 5863 - 5881 (2012/09/22)
The copper-catalyzed radical cyclization (RC) of N-α-perchloroacyl cyclic ketene-N,X(X=O, NR, S)-acetals was studied. While the RC of N-acyl ketene-N,O-acetals was unsuccessful, the 5-endo cyclization of the other ketene acetals provided much better results, with the following order of cyclization efficiency: hexa-atomic cyclic ketene-N,NR-acetalspenta-atomic cyclic ketene-N,S-acetalshexa-atomic cyclic ketene-N,S-acetals. Invariably the catalytic cycle begins with the formation of a carbamoyl methyl radical. This leads to a cascade of reactions, including a radical polar crossover step, which ends with the formation of the maleimide nucleus, or precursors of this. Products from the RC of the hexa-atomic cyclic ketene-N,S-acetals, were efficiently transformed into disubstituted maleic anhydrides.
Platinum catalysed hydrolytic amidation of unactivated nitriles
Cobley, Christopher J.,Van Den Heuvel, Marco,Abbadi, Abdelilah,De Vries, Johannes G.
, p. 2467 - 2470 (2007/10/03)
The platinum(II) complex, [(Me2PO··H··OPMe2)PtH(PMe2OH)], efficiently catalyses the direct conversion of unactivated nitriles to N- substituted amides with both primary and secondary amines. Possible mechanisms for this reaction are discussed and evidence for initial amidine formation is reported. Isolated yields vary from 51-89%. (C) 2000 Elsevier Science Ltd.
