α-Chloro-m-tolyl-N-phenylcarbamat, also known as aldicarb, is a synthetic organophosphorus compound widely used as an insecticide and acaricide. It is a white crystalline solid with the chemical formula C9H8ClNOS2. Aldicarb is highly toxic to both mammals and insects, acting as a potent cholinesterase inhibitor, which disrupts the nervous system by preventing the breakdown of acetylcholine. This results in overstimulation of the nervous system, leading to paralysis and death in target pests. Due to its high toxicity, aldicarb is classified as a Restricted Use Pesticide in many countries, and its use is limited to professional applicators. It is primarily used to control soil-dwelling pests, such as nematodes, and is also effective against a variety of insects, including aphids, mites, and whiteflies. However, concerns about its potential health risks and environmental impact have led to a decrease in its use and a push for alternative, less toxic pest control methods.
The CAS Registry Mumber 22134-41-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,2,1,3 and 4 respectively; the second part has 2 digits, 4 and 1 respectively. Calculate Digit Verification of CAS Registry Number 22134-41: (7*2)+(6*2)+(5*1)+(4*3)+(3*4)+(2*4)+(1*1)=64 64 % 10 = 4 So 22134-41-4 is a valid CAS Registry Number.
