2,2-dimethyl-3-pentachlorophenoxy-cyclopropanecarboxylic acid ethyl ester, also known as ethyl 2,2-dimethyl-3-(2,3,4,5,6-pentachlorophenoxy) cyclopropanecarboxylate, is a complex organic compound with the chemical formula C15H15Cl5O3. 2,2-dimethyl-3-pentachlorophenoxy-cyclopropanecarboxylic acid ethyl ester is a derivative of cyclopropanecarboxylic acid, featuring a cyclopropane ring with a pentachlorophenoxy group attached to the 3-position and an ethyl ester group at the 2,2-dimethyl position. It is a white crystalline solid with a molecular weight of 426.5 g/mol. This chemical has been used as an insecticide, particularly for the control of termites and other wood-boring insects, due to its ability to disrupt the endocrine system of these pests. However, its use has been restricted or banned in many countries due to concerns over its environmental persistence and potential health risks to humans and wildlife.
The CAS Registry Mumber 5893-39-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,8,9 and 3 respectively; the second part has 2 digits, 3 and 9 respectively. Calculate Digit Verification of CAS Registry Number 5893-39: (6*5)+(5*8)+(4*9)+(3*3)+(2*3)+(1*9)=130 130 % 10 = 0 So 5893-39-0 is a valid CAS Registry Number.
