103440-03-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 103440-03-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,3,4,4 and 0 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 103440-03:
(8*1)+(7*0)+(6*3)+(5*4)+(4*4)+(3*0)+(2*0)+(1*3)=65
65 % 10 = 5
So 103440-03-5 is a valid CAS Registry Number.

Study of a new 3D MOF and its adsorption, slow release and biological activity in water-soluble and oil-soluble pesticides

Borui, Li,He, Junjie,Linxin, Deng,Nana, Wang,Song, Li

, (2020)

The ligands of (E)-bis(p-3-nitrobenzoic acid) vinyl (C16H10N2O8) were synthesized in three steps, and then the MOF-Zn2(EBNB)2(BPY)2·2H2O was synthesized by solvotherma

Kinetics of the reaction of sodium arylthiolates with nitro-carboxybenzyl halide derivatives

Hamed, Ezzat A.,El-Bardan, Ali A.,El-Mallah, Nabila M.

, p. 283 - 289 (2007/10/03)

The rate constants for the reactions of 4-halomethyl-3-nitrobenzoic acids, the nonnitro derivatives, and their ethyl esters with arylthiolates were measured at different temperatures. It was found that the retardation in rate constants compared to benzyl halides is due to the electrostatic repulsion between the electronegative substituents (COO- and/or NO2) in the substrates and thiolate ions Good correlations between log K2 values of the acids and carbon basicities of thiolates were found while log k2 values of the esters show good straight lines with Hammett a constants, pKa. and carbon basicities of arylthiolates.
