338949-21-6 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 338949-21-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,3,8,9,4 and 9 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 338949-21:
(8*3)+(7*3)+(6*8)+(5*9)+(4*4)+(3*9)+(2*2)+(1*1)=186
186 % 10 = 6
So 338949-21-6 is a valid CAS Registry Number.

A highly efficient heterogeneous ruthenium-catalysed oxidative α-cyanation of tertiary amines leading to α-aminonitriles

Wang, Xiaoming,Xiao, Ruian,Ai, Jingting,Cai, Mingzhong

, p. 576 - 580 (2017/11/14)

Oxidative α-cyanation of tertiary amines was achieved by using an MCM-41-immobilised N-alkylethylenediamine ruthenium(III) complex (MCM-41-2N-RuCl3) as catalyst in MeOH at 60 oC in the presence of H2O2 as oxidant and NaCN

Synthesis of new quinoxaline derivatives by reductive cyclization of various 1-(2-nitrophenyl)-2-cyanoamines

Renaud, Tristan,Hurvois, Jean-Pierre,Uriac, Philippe

, p. 987 - 996 (2007/10/03)

The electrochemical cyanation of various six-membered N-(2-nitrophenyl) heterocyclic amines, including piperidine, morpholine, thiomorpholine, and N-Boc-protected piperazine derivatives, was investigated. The expected cyanoamines 5 were obtained in good y
