O-Methyl-O-(2-Chlor-4-tert.-butyl-phenyl)-phosphorochlorido-thionat, also known as Chlorpyrifos, is an organophosphorus compound widely used as an insecticide. It is a colorless to pale yellow oily liquid with a chemical formula of C9H11Cl3NO3PS. Chlorpyrifos works by inhibiting the enzyme acetylcholinesterase in insects, leading to the accumulation of acetylcholine and causing paralysis and death. It is effective against a broad spectrum of pests, including aphids, mites, and various caterpillars, and is commonly used in agriculture, forestry, and public health. However, due to its potential health and environmental risks, its use has been restricted or banned in several countries.

Check Digit Verification of cas no
The CAS Registry Mumber 955-92-0 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 9,5 and 5 respectively; the second part has 2 digits, 9 and 2 respectively.Calculate Digit Verification of CAS Registry Number 955-92:
(5*9)+(4*5)+(3*5)+(2*9)+(1*2)=100
100 % 10 = 0
So 955-92-0 is a valid CAS Registry Number.
