544-92-3 Usage

General Description

Copper(I) cyanide, also known as cuprous cyanide, is an inorganic compound with a chemical formula of CuCN. It is a white, crystalline solid that does not dissolve in water but is soluble in potassium cyanide solution and slightly soluble in ammonia solution. It is highly toxic and can release hydrogen cyanide gas when heated or in contact with acid. Copper(I) cyanide is primarily used in electroplating, metallurgy, and as a catalyst in chemical reactions due to its ability to form complexes with various molecules. The production of copper(I) cyanide involves the reaction between copper(I) salts with cyanide.

Check Digit Verification of cas no

The CAS Registry Mumber 544-92-3 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 5,4 and 4 respectively; the second part has 2 digits, 9 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 544-92:
(5*5)+(4*4)+(3*4)+(2*9)+(1*2)=73
73 % 10 = 3
So 544-92-3 is a valid CAS Registry Number.

METHOD FOR PREPARING LAMOTRIGINE AND ITS INTERMEDIATE 2,3-DICHLOROBENZOYL CHLORIDE

-

Page/Page column 14, (2010/11/29)

The invention relates to an improved method for preparing 3,5-diamino-6-(2,3-dichlorophenyl)-1,2,4-triazine, also commonly known as lamotrigine. The present invention also relates to a method for preparing the intermediate 2,3-dichlorobenzoyl chloride, which comprises the synthesis by photochlorination of 2,3-dichlorobenzotrichloride followed by hydrolysis thereof. Said 2,3-dichlorobenzoyl chloride intermediate is useful for preparing lamotrigine.

Electrochemistry of cyanocopper thiomolybdates and thiotungstates: Redox-based interconversion of species

Kony, Michael,Bond, Alan M.,Wedd, Anthony G.

, p. 4521 - 4525 (2008/10/08)

[MoS4]2- and its 1:1 and 1:2 CuCN adducts [(CN)CuS2MoS2]2- and [(CN)CuS2MoS2Cu(CN)]2- each exhibit electrochemically reversible one-electron reductions in MeCN at fast scan rates (>500 mV s-1). At lower scan rates, the reduced adduct species are unstable to dissociation of CuCN, leading to interconversion of the three anions. The tungsten analogues show similar properties.
