O-ethyl O-(3-methyl-4-nitrophenyl) phenylphosphonothioate, 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 phosphonothioate moiety, with a 3-methyl-4-nitrophenyl group and a phenyl group. O-ethyl O-(3-methyl-4-nitrophenyl) phenylphosphonothioate 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 to mammals and potential environmental concerns, including persistence in the environment and bioaccumulation, its use has been restricted or banned in many countries. The compound's chemical properties and historical use highlight the complex balance between the benefits of chemical pest control and the need for safety and environmental stewardship.

898-77-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 898-77-1 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 8,9 and 8 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 898-77:
(5*8)+(4*9)+(3*8)+(2*7)+(1*7)=121
121 % 10 = 1
So 898-77-1 is a valid CAS Registry Number.
