Ethylphosphonodithioic acid O-ethyl S-(o-tolyl) ester, also known as EPN or O-ethyl S-(o-tolyl) ethylphosphonodithioate, is a chemical compound with the molecular formula C12H17OPS2. It is an organophosphorus compound that belongs to the class of phosphonodithioic acids. EPN is primarily used as an insecticide and acaricide, targeting a wide range of pests such as aphids, mites, and caterpillars. It works by inhibiting the activity of acetylcholinesterase, an enzyme essential for the proper functioning of the nervous system in insects. This results in the accumulation of acetylcholine, leading to overstimulation and paralysis of the nervous system, ultimately causing the death of the pest. EPN is known for its effectiveness against resistant pest populations and is used in agriculture to protect crops from damage caused by various insects. However, due to its potential environmental and health risks, its use is regulated in many countries.

3099-88-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 3099-88-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,0,9 and 9 respectively; the second part has 2 digits, 8 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 3099-88:
(6*3)+(5*0)+(4*9)+(3*9)+(2*8)+(1*8)=105
105 % 10 = 5
So 3099-88-5 is a valid CAS Registry Number.
