Phosphorothioic acid, O,O-diethyl S-[2-[methyl(4-methylphenyl)amino]ethyl] ester, also known as EPN, is a complex organic compound with the chemical formula C14H22NOPS. It is a type of organophosphorus compound, specifically a phosphorothioate, which is characterized by the presence of a phosphorus atom bonded to sulfur and oxygen atoms. EPN is a colorless to pale yellow liquid with a strong, pungent odor. It is primarily used as an insecticide, particularly for the control of various pests in agriculture. The compound works by inhibiting the activity of acetylcholinesterase, an enzyme crucial for the proper functioning of the nervous system in insects, leading to their paralysis and death. Due to its toxicity and potential environmental impact, the use of EPN has been restricted or banned in many countries.

4294-43-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 4294-43-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,2,9 and 4 respectively; the second part has 2 digits, 4 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 4294-43:
(6*4)+(5*2)+(4*9)+(3*4)+(2*4)+(1*3)=93
93 % 10 = 3
So 4294-43-3 is a valid CAS Registry Number.
