52843-93-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 52843-93-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,2,8,4 and 3 respectively; the second part has 2 digits, 9 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 52843-93:
(7*5)+(6*2)+(5*8)+(4*4)+(3*3)+(2*9)+(1*3)=133
133 % 10 = 3
So 52843-93-3 is a valid CAS Registry Number.

Facile synthesis and herbicidal activity of novel multisubstituted pyridine derivatives

Ren, Qingyun,Mo, Wenyan,Gao, Ling,He, Hongwu,Gu, Yucheng

experimental part, p. 171 - 178 (2010/04/24)

(Chemical Equation Presented) Ketene N,S-acetals reacted with β-ketoesters in the presence of Zn(NO3)2 · 6H2O as catalyst, in ethanol solvent, giving 6-alkylsulfanylpyridines 4 in good yields without complicated purificati

3-Alkylthio-, 3-alkylsulfinyl-, and 3-alkylsulfonylisothiazole derivatives as herbicides

, (2008/06/13)

A new class of herbicidal compounds consisting of 1-alkyl- and 1,1-dialkyl-3-(3,4-substituted-5-isothiazolyl)ureas and N-(3,4-substituted-5-isothiazolyl)-alkanamides in which the 3-substituent consists of alkylthio, alkylsulfinyl, and alkylsulfonyl, and the 4-substituent consists of cyano, and carbamoyl, exhibits preemergence and postemergence herbicidal activity, controlling effectively the growth of a wide spectrum of grassy and broad-leaved plant species. The synthesis of members of this class is described in detail, and the utility of representative compounds is exemplified.
