O-(2-Chloro-4-nitrophenyl)O-methyl-ethylphosphonothioate, also known as Chlorpyrifos, is an organophosphorus compound widely used as an insecticide. It is a broad-spectrum pesticide that targets a variety of pests, including insects, mites, and nematodes. Chlorpyrifos works by inhibiting the enzyme acetylcholinesterase, which is essential for the proper functioning of the nervous system in insects. This inhibition leads to the accumulation of acetylcholine, causing overstimulation and ultimately death of the target pests. The chemical is effective against a range of agricultural and household pests, making it a popular choice for pest control. However, due to its potential health and environmental risks, including toxicity to humans and non-target species, as well as persistence in the environment, there has been a growing concern and regulatory efforts to limit its use in some regions.

2917-21-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 2917-21-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,9,1 and 7 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 2917-21:
(6*2)+(5*9)+(4*1)+(3*7)+(2*2)+(1*1)=87
87 % 10 = 7
So 2917-21-7 is a valid CAS Registry Number.
