Dithiophosphorsaeure-O-butylester-S-phenylester-butylamid, also known as O,O'-dibutyl S-phenyl phosphorodithioate or dibutyl phenyl phosphorothionate, is a chemical compound with the molecular formula C16H23O2PS2. It is an organophosphorus compound that belongs to the class of dithiophosphates. Dithiophosphorsaeure-O-butylester-S-phenylester-butylamid is primarily used as an insecticide and acaricide in agriculture, targeting pests such as mites, aphids, and whiteflies. It works by inhibiting the acetylcholinesterase enzyme in the nervous system of insects, leading to their paralysis and eventual death. Due to its potential toxicity and environmental impact, its use is regulated in many countries, and alternative, less harmful pesticides are being developed.
The CAS Registry Mumber 4124-27-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,1,2 and 4 respectively; the second part has 2 digits, 2 and 7 respectively. Calculate Digit Verification of CAS Registry Number 4124-27: (6*4)+(5*1)+(4*2)+(3*4)+(2*2)+(1*7)=60 60 % 10 = 0 So 4124-27-0 is a valid CAS Registry Number.
