140163-89-9 Usage
General Description
O-ethyl S-propyl [(2E)-2-(cyanoimino)-3-ethylimidazolidin-1-yl]phosphonothioate is a chemical compound that belongs to the class of organophosphorus compounds. It is commonly used as a pesticide and insecticide, particularly for controlling agricultural pests. O-ethyl S-propyl [(2E)-2-(cyanoimino)-3-ethylimidazolidin-1-yl]phosphonothioate works by inhibiting the activity of acetylcholinesterase, an enzyme that is essential for the proper functioning of the nervous system in insects. By disrupting the nervous system, it ultimately leads to paralysis and death of the pests. However, due to its toxic nature, it is important to handle this chemical with caution and follow safety guidelines when using it.
Check Digit Verification of cas no
The CAS Registry Mumber 140163-89-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,0,1,6 and 3 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 140163-89:
(8*1)+(7*4)+(6*0)+(5*1)+(4*6)+(3*3)+(2*8)+(1*9)=99
99 % 10 = 9
So 140163-89-9 is a valid CAS Registry Number.

Paragraph 0014, (2016/12/07)
PROBLEM TO BE SOLVED: To provide a method for producing O-ethyl S-n-propyl(E)-[2-(cyanoimino)-3-ethylimidazolidin-1-yl]phosphonothioate at high purity and high yield. SOLUTION: In this method, O-ethyl S-n-propyl(E)-[2-(cyanoimino)-3-ethylimidazolidin-1-yl]phosphonothioate is produced by making 2-(cyanoimino)-1-ethylimidazolidine react with O-ethyl-S-n-propylphosphorochloridethioate in the presence of an inert solvent and basic substance. In this method, as the basic substance, alkali metal hydroxide, alkaline earth metal hydroxide, or metal alkoxide is used. COPYRIGHT: (C)2013,JPOandINPIT
