157683-72-2 Usage
General Description
"2,6-Dichlorophenyl 4-chlorophenyl ether" is a chemical compound with a molecular formula C12H6Cl3O that belongs to the class of organochlorine compounds. It is a colorless solid that is insoluble in water but soluble in organic solvents. This chemical is commonly used as a pesticide and as a fungicide in agriculture and horticulture. It works by disrupting the cell membranes of fungi, bacteria, and insects, leading to their death. However, due to its potential environmental and health risks, its use has been limited in many countries. Studies have also suggested that it may have toxic effects on aquatic life and may bioaccumulate in the food chain.
Check Digit Verification of cas no
The CAS Registry Mumber 157683-72-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,7,6,8 and 3 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 157683-72:
(8*1)+(7*5)+(6*7)+(5*6)+(4*8)+(3*3)+(2*7)+(1*2)=172
172 % 10 = 2
So 157683-72-2 is a valid CAS Registry Number.

Synthesis, Structure Verification, and Chromatographic Relative Retention Times for Polychlorinated Diphenyl Ethers
Nevalainen, Tapio,Koistinen, Jaana,Nurmela, Pirjo
, p. 1341 - 1347 (2007/10/03)
Fifty-four polychlorinated diphenyl ether (PCDEs) congeners were synthesized, and their structures were confirmed by mass spectrometry and proton magnetic resonance spectroscopy. The gas chromatographic relative retention times (RRT) for the PCDEs were determined relative to a reference standard, -tetrachlorobiphenyl (PCB 77) on the fused silica capillary columns of SE-54 and OV-1701. The retention times for PCDEs increased with the increasing number of vicinal chlorines within a series of isomers. The chlorine substitution patterns of PCDEs were used to develop a method for predicting RRTs for congeners that were not synthesized.
