O-ethyl bis(2,2-dimethylaziridin-1-yl)phosphinothioate, also known as EPN, is an organophosphorus compound that was once widely used as an insecticide. It is characterized by its chemical structure, which includes an ethyl group attached to a phosphorus atom, which is further bonded to two 2,2-dimethylaziridin-1-yl groups. O-ethyl bis(2,2-dimethylaziridin-1-yl)phosphinothioate was particularly effective against a variety of pests due to its ability to inhibit the enzyme acetylcholinesterase, leading to the accumulation of acetylcholine in the nervous system of insects, which results in paralysis and death. However, due to its high toxicity and potential health risks to humans and the environment, its use has been largely discontinued in many countries. The compound's chemical properties and historical use highlight the complex relationship between the development of effective pest control agents and the need for safety in agricultural and public health practices.

3678-20-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 3678-20-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,6,7 and 8 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 3678-20:
(6*3)+(5*6)+(4*7)+(3*8)+(2*2)+(1*0)=104
104 % 10 = 4
So 3678-20-4 is a valid CAS Registry Number.
