α-Cyclohexyl-α-isopropyl-cyanessigsaeure, also known as (+)-Cis-Permethrin, is a synthetic pyrethroid insecticide derived from natural pyrethrins found in the flowers of the Chrysanthemum cinerariifolium plant. It is a potent neurotoxin that acts on the nervous system of insects, leading to paralysis and death. The chemical structure consists of a cyclohexane ring and an isopropyl group, with a cyano group attached to the alpha carbon. Permethrin is widely used in agriculture, veterinary medicine, and public health for controlling a variety of pests, including mosquitoes, flies, ticks, and mites. It is known for its rapid knockdown effect and low mammalian toxicity, making it a popular choice for both indoor and outdoor applications. However, due to its potential environmental impact and concerns over resistance development in pests, its use is regulated in many countries.
The CAS Registry Mumber 91553-94-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,1,5,5 and 3 respectively; the second part has 2 digits, 9 and 4 respectively. Calculate Digit Verification of CAS Registry Number 91553-94: (7*9)+(6*1)+(5*5)+(4*5)+(3*3)+(2*9)+(1*4)=145 145 % 10 = 5 So 91553-94-5 is a valid CAS Registry Number.
