109692-20-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 109692-20-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,9,6,9 and 2 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 109692-20:
(8*1)+(7*0)+(6*9)+(5*6)+(4*9)+(3*2)+(2*2)+(1*0)=138
138 % 10 = 8
So 109692-20-8 is a valid CAS Registry Number.

Synthesis, spectroscopic studies and crystal structures of ReI(CO)3(NN)Cl complexes with N,Nae-bis(substituted benzylidene)ethane-1,2-diamine Schiff base ligands

Mirkhani, Valiollah,Kia, Reza,Milic, Dalibor,Vartooni, Akbar Rostami,Matkovic-Calogovic, Dubravka

, p. 81 - 87 (2010)

Four new Re(I) tricarbonyl-diimine complexes were prepared by reaction of Re(CO)5Cl with N,Nae-bis(substituted benzylidene)ethane-1,2-diamine Schiff base ligands. These compounds were characterized by physico-chemical methods, and their crystal

One-pot synthesis of imidazolinium salts via the ring opening of tetrahydrofuran

Huang, Yong-Qing,Zhao, Yue,Wang, Peng,Okamura, Taka-Aki,Laforteza, Brian N.,Lu, Yi,Sun, Wei-Yin,Yu, Jin-Quan

supporting information, p. 12430 - 12433 (2017/10/06)

A new one-pot synthesis of C2-hydroxypropyl-substituted imidazolinium salts via the ring opening of tetrahydrofuran (THF) with N,N′-disubstituted diamines has been developed. Preliminary studies of the reaction mechanism suggest the CO2-promoted oxidative ring opening of THF followed by Hg(ii)-mediated oxidation of an imidazolidine intermediate. These novel C2-substituted imidazolinium salts have shown to be active catalysts for the aza-Diels-Alder reactions.

Synthesis of new antifungal 1,2,4-bis-oxadiazolines using cycloaddition reaction of nitrile oxide with bis-Schiff base

Toumi, Ahmed,Daami-Remadi, Mejda,Jannet, Hichem Ben

, p. 922 - 928 (2013/08/15)

A series of arylaldehydes and acetophenone when treated with 1,2-ethanediamine afford the bis-Schiff bases N,N'- bis(arylidene)-ethane-l,2- diamines 1-8, N,N'-bis(arylmethylene)-ethane-l,2-diamines 9-10 and the N,N'-bis(l- phenylethylidene)-ethane-l,2-dia
