Dithiophosphoric acid O,O-diethyl S-[(4-chlorophenyl)phenylmethyl] ester, also known as Fenthion, is an organophosphorus compound widely used as an insecticide and acaricide. It is a colorless to pale yellow liquid with a chemical formula of C12H15ClO3PS2. Fenthion is effective against a broad spectrum of pests, including insects and mites, and is commonly applied in agriculture to protect crops from damage. The compound works by inhibiting the activity of acetylcholinesterase, an enzyme essential for the proper functioning of the nervous system in insects. This inhibition leads to the accumulation of acetylcholine, causing overstimulation and ultimately paralysis and death of the target pests. Fenthion is also used in veterinary medicine for controlling ectoparasites in animals. Due to its potential toxicity to humans and the environment, it is important to follow proper safety measures and regulations when using this chemical.

973-28-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 973-28-4 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 9,7 and 3 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 973-28:
(5*9)+(4*7)+(3*3)+(2*2)+(1*8)=94
94 % 10 = 4
So 973-28-4 is a valid CAS Registry Number.
