3-(4-chloro-phenoxy)-2,2-dimethyl-cyclopropanecarboxylic acid ethyl ester, also known as cypermethrin, is a synthetic pyrethroid insecticide derived from natural pyrethrins found in chrysanthemum flowers. 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 mosquitoes, flies, and other insects. It is also used in veterinary medicine and public health for the control of ectoparasites on animals and for the treatment of head lice in humans. Due to its effectiveness and low mammalian toxicity, cypermethrin is considered a safer alternative to older, more toxic insecticides. However, it is important to use it responsibly and follow label instructions to minimize potential risks to non-target organisms and the environment.
The CAS Registry Mumber 5894-97-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,8,9 and 4 respectively; the second part has 2 digits, 9 and 7 respectively. Calculate Digit Verification of CAS Registry Number 5894-97: (6*5)+(5*8)+(4*9)+(3*4)+(2*9)+(1*7)=143 143 % 10 = 3 So 5894-97-3 is a valid CAS Registry Number.
