2391-80-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 2391-80-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,3,9 and 1 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 2391-80:
(6*2)+(5*3)+(4*9)+(3*1)+(2*8)+(1*0)=82
82 % 10 = 2
So 2391-80-2 is a valid CAS Registry Number.

Cu-mediated one-pot three-component synthesis of 3-N-substituted 1,4,2-benzodithiazine 1,1-dioxide derivatives

Dong, Wei,Ge, Zemei,Wang, Xin,Li, Ridong,Li, Runtao

, (2020/07/03)

A novel and efficient copper-catalyzed one-pot procedure for the synthesis of 3-N-substituted 1,4,2-benzodithiazine 1,1-dioxide derivatives from 2-halobenzenesulfonamides, amines and CS2 is described. The reaction proceeds through Ullmann-type S-arylation, intramolecular addition of NH2 with C[dbnd]S and dehydrosulfide, which provides a new and useful strategy for construction of cyclic aromatic sulfonamides.

Metal-sulphur Bond Enthalpy Determination of Di-n-Butyldithiocarbamate Chelates of Zinc, Cadmium and Mercury

Souza, Antonio G. de,Souza, Jose H. de,Airoldi, Claudio

, p. 1751 - 1754 (2007/10/02)

The standard molar enthalpies of formation of crystalline n2)2> (M = Zn, Cd or Hg), determined through reaction-solution calorimetry at 298.15 K, were found to be -471.23 +/- 3.90, -440.74 +/- 3.79 and -319.29 +/- 3.38 kJ mol-1, respectively.The corresponding molar enthalpies of sublimation, 107 +/- 3, 123 +/- 3 and 195 +/- 3 kJ mol-1, were estimated by means of differential scanning calorimetry.From the standard molar enthalpies of formation of the gaseous chelates, -364 +/- 5, 318 +/- 5 and -124 +/- 5 kJ mol-1, the homolytic and heterolytic mean metal-sulphur bond enthalpies were calculated.The homolytic enthalpies decrease from zinc to mercury, while the heterolytic values are almost constant.

Enthalpies of formation of crystalline dialkylammoniumdialkyldithiocarbamates: alkyl = ethyl, n-propyl, i-propyl, n-butyl, and i-butyl

Silva, Manuel A. V. Ribeiro Da,Reis, Ana M. V.,Pilcher, Geoffrey

, p. 837 - 844 (2007/10/02)

The standard (p0 = 101.325 kPa) molar enthalpies of formation of some crystalline dialkylammoniumdialkyldithiocarbamates were determined at 298.15 K by both solution-reaction calorimetry and by rotating-bomb calorimetry.The values from the two methods agreed to within the limits of experimental error, giving the weighted mean values: R = Ethyl, ΔfH0m(R2NH2S2CNR2, cr): -249.2+/-2.2 kJ*mol-1; R = n-Propyl: -353.2+/-1.3 kJ*mol-1; R = i-Proyl: -349.6+/-1.3 kJ*mol-1; R = n-Butyl: -461.3+/-1.6 kJ*mol-1; R = i-Butyl: -463.8+/-1.4 kJ*mol-1.
