22100-61-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 22100-61-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,2,1,0 and 0 respectively; the second part has 2 digits, 6 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 22100-61:
(7*2)+(6*2)+(5*1)+(4*0)+(3*0)+(2*6)+(1*1)=44
44 % 10 = 4
So 22100-61-4 is a valid CAS Registry Number.

Synthesis and photophysical properties of ruthenium(ii) polyimine complexes decorated with flavin

Guo, Huimin,Zhu, Lijuan,Dang, Can,Zhao, Jianzhang,Dick, Bernhard

, p. 17504 - 17516 (2018/07/06)

A bipyridine ruthenium(ii) complex (Ru-1) with a flavin moiety connected to one of the bipyridine ligands via an acetylene bond was designed and synthesized, and its photophysical properties were investigated. Compared with the tris(bipyridine) Ru(ii) com

Cu-Al hydrotalcite: An efficient and reusable ligand-free catalyst for the coupling of aryl chlorides with aliphatic, aromatic, and N(H)-heterocyclic amines

Sreedhar,Arundhathi,Linga Reddy,Amarnath Reddy,Lakshmi Kantam

experimental part, p. 2517 - 2522 (2010/03/24)

Copper-aluminum hydrotalcite catalysts were effectively used in the coupling of aryl chlorides with aliphatic, aromatic, and N(H)-heterocyclic amines to afford the corresponding N-alkylated/arylated amines in excellent yields. The catalyst was quantitatively recovered from the reaction by simple filtration and reused for a number of cycles with almost consistent activity. Georg Thieme Verlag Stuttgart.

O- and N-Alkylsubstituted 2-(2'-Hydroxyphenyl)-benzimidazoles and -1,3,4-Oxadiazoles as Complexing and Extracting Agents for Copper-II-Ions

Beger, J.,Wagner, G.,Uhlig, E.,Dinjus, U.

, p. 708 - 718 (2007/10/02)

2-(2'-Alkoxyphenyl)-benzimidazoles 1, 1-alkyl-2-(2'-hydroxyphenyl)-benzimidazoles 2, 2-(2'-hydroxy-4'-alkoxyphenyl)-benzimidazoles 3, 2-(2',4'-dialkoxyphenyl)-benzimidazoles 4 and 1-alkyl-2-(2'-hydroxy-5'-nitrophenyl)-benzimidazoles 7 are synthesized by condensation of 2-hydroxybenzoic acid derivatives and o-phenylendiamine or its derivatives.Alkyl chains (C4, C8 or C12) are introduced by alkylation before or after the ring closure in order to increase the solubility of the reagent in toluene or n-octane.Furthermore the extraction properties of the benzimidazoles are investigated.Also some new analogous compounds of the benzothiazole and the 1,3,4-oxadiazole series were synthesized.
