3-(2,4-dichloro-phenoxy)-2,2-dimethyl-cyclopropanecarboxylic acid ethyl ester, commonly known as cypermethrin, is a synthetic pyrethroid insecticide derived from natural pyrethrins. It is a potent neurotoxin that acts on the nervous system of insects, causing paralysis and death by disrupting the flow of sodium ions across nerve cell membranes. Cypermethrin is widely used in agriculture to control a broad spectrum of pests, including aphids, mites, and various types of caterpillars. It is also used in veterinary medicine and for public health purposes to control mosquitoes, flies, and other disease-carrying insects. Due to its effectiveness and low mammalian toxicity, cypermethrin is considered a valuable tool in integrated pest management strategies. However, it is important to use it responsibly and in accordance with label instructions to minimize potential risks to non-target organisms and the environment.
The CAS Registry Mumber 5842-40-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,8,4 and 2 respectively; the second part has 2 digits, 4 and 0 respectively. Calculate Digit Verification of CAS Registry Number 5842-40: (6*5)+(5*8)+(4*4)+(3*2)+(2*4)+(1*0)=100 100 % 10 = 0 So 5842-40-0 is a valid CAS Registry Number.
