1,2,3,4,4,5,6-Heptachlorcyclohexyl-trichloracetat, also known as heptachlor epoxide, is a highly toxic organochlorine compound derived from the insecticide heptachlor. It is formed as a metabolite of heptachlor and is more persistent and toxic than its parent compound. This chemical is a white crystalline solid with a chemical formula of C10H5Cl7O2. Due to its lipophilic nature, it tends to accumulate in fatty tissues and can be found in the environment, particularly in soil and water. Heptachlor epoxide is classified as a persistent organic pollutant (POP) and is known to cause adverse effects on the nervous system, reproductive system, and endocrine system in humans and wildlife. It has been banned or restricted in many countries due to its potential health risks and environmental persistence.
The CAS Registry Mumber 7027-19-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,0,2 and 7 respectively; the second part has 2 digits, 1 and 9 respectively. Calculate Digit Verification of CAS Registry Number 7027-19: (6*7)+(5*0)+(4*2)+(3*7)+(2*1)+(1*9)=82 82 % 10 = 2 So 7027-19-2 is a valid CAS Registry Number.
