5286-73-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 5286-73-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,2,8 and 6 respectively; the second part has 2 digits, 7 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 5286-73:
(6*5)+(5*2)+(4*8)+(3*6)+(2*7)+(1*3)=107
107 % 10 = 7
So 5286-73-7 is a valid CAS Registry Number.

Selective Sulfur Oxygenation in Phosphoroamidate, Thionophosphate, and Thiophosphate Agrochemicals by Perfluoro-cis-2,3-dialkyloxaziridine

Terreni, Marco,Pregnolato, Massimo,Resnati, Giuseppe,Benfenati, Emilio

, p. 7981 - 7992 (2007/10/02)

Several organophsophorus agrochemicals 2a-g with thioether, phosphoramidic, phosphorothioic, and phosphorothionic functions were reacted with perfluoro-cis-2-n-butyl-3-n-propyloxaziridine 1.The selective oxygenation of sulfide function to give sulfoxide derivatives 3a-g occured in high yields without overoxidation to sulfone products.Sulfoxides 3a-e were further oxidized under mild conditions to the corresponding sulfones 4a-e.All the products are themselves of interest as analytical environmental standards and their preparation is described in detail.
