O,O-dipropyl (5-methylpyridin-2-yl)phosphoramidothioate, also known as 5-methyl-2-pyridinyl dipropyl phosphoramidothioate, is a chemical compound with the molecular formula C14H22NOPS. It is an organophosphorus compound that belongs to the class of phosphoramidates. O,O-dipropyl (5-methylpyridin-2-yl)phosphoramidothioate is characterized by the presence of a phosphorus atom bonded to two propyl groups, a 5-methylpyridin-2-yl group, and a sulfur atom. It is often used as an insecticide and acaricide in agriculture, targeting a variety of pests due to its neurotoxic properties. The compound works by inhibiting the enzyme acetylcholinesterase, which is crucial for the proper functioning of the nervous system in insects. This inhibition leads to the accumulation of acetylcholine, causing overstimulation and ultimately the death of the pest. Due to its potential health and environmental risks, its use is regulated in many countries.

3143-76-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 3143-76-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,1,4 and 3 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 3143-76:
(6*3)+(5*1)+(4*4)+(3*3)+(2*7)+(1*6)=68
68 % 10 = 8
So 3143-76-8 is a valid CAS Registry Number.
