5339-83-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 5339-83-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,3,3 and 9 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 5339-83:
(6*5)+(5*3)+(4*3)+(3*9)+(2*8)+(1*3)=103
103 % 10 = 3
So 5339-83-3 is a valid CAS Registry Number.

Titanium(IV) enolates of 2-nitrocarboxylic esters and their oxidative chlorinationa convenient route to α-chloro-α-nitrocarboxylates

Ciez, Dariusz,Kalinowska-T?us?cik, Justyna

supporting information; experimental part, p. 267 - 271 (2012/03/11)

A new method for the synthesis of 2-chloro-2-nitrocarboxylic esters from 2-nitrocarboxylates is described. The procedure consists of the oxidative chlorination of titanium(IV) enolates of 2-nitro esters in the presence of ammonium nitrate. Esters of 2-chloro-2-nitrocarboxylic acids are formed in very good to quantitative yields. Application of this method for the chlorination of α,α′-dinitrodicarboxylates leads to α,α′- dichloro-α,α′-dinitrocarboxylic esters with high meso-diastereoselectivity. The absence of ammonium nitrate from the reaction mixture affects the reduction of nitro groups and leads to partial transformation of 2-nitrocarboxylic esters into 2-(hydroxyimino)carboxylates.
