35757-19-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 35757-19-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,5,7,5 and 7 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 35757-19:
(7*3)+(6*5)+(5*7)+(4*5)+(3*7)+(2*1)+(1*9)=138
138 % 10 = 8
So 35757-19-8 is a valid CAS Registry Number.

Nucleophilic Substitution Reactions of 1-Halogeno-4-COR-2-nitrobenzenes and 1-Halogeno-6-COR-2-nitrobenzenes with Sodium Benzenethiolate and Piperidine. Can an "Inverted Built-in Solvation" Be Responsible for the Peculiar Activation by an o-Carboxamido Group in SNAr Reactions with an Anionic Nucleophile?

Arnone, Caterina,Consiglio, Giovanni,Frenna, Vincenzo,Spinelli, Domenico

, p. 3093 - 3097 (2007/10/03)

A kinetic study of the title reactions has allowed an interpretation of the higher efficiency of an o-carboxamido group with respect to an o-carbomethoxy group in activating the benzenethiolate-dehalogenation reactions in methanol (kCONH2/kCO2Me 2.2-3.0) as due to an interaction between the anionic nucleophile and the hydrogen atoms of the carboxamido group. An inversion of the activating power of the two groups (kCONH2/kCO2Me 0.14) in the reactions with the same nucleophile has been observed when they are in a para-position. Moreover, for piperidino-dehalogenation reactions in methanol kCONH2/kCO2Me ratios less than unity (0.2-0.6) have been observed independently of the position (ortho or para) of the carboxamido and carbomethoxy groups with respect to the reaction center.
