It is characterized by the presence of six chlorine atoms, which are strategically placed at positions 4, 5, 6, 7, 8, and 8 on the molecule. The compound also features a tetrahydro-4,7-methanoisobenzofuran core, which is a reduced form of isobenzofuran, a heterocyclic aromatic organic compound. The 1,3-dione functional group indicates the presence of two carbonyl groups (C=O) at the 1st and 3rd positions of the molecule. 4,5,6,7,8,8-hexachloro-3a,4,7,7a-tetrahydro-4,7-methanoisobenzofuran-1,3-dione is known for its stability and resistance to degradation, which has led to its use in various industrial applications, particularly as a pesticide. However, due to its persistence in the environment and potential health risks, its production and use have been restricted or banned in many countries.
The CAS Registry Mumber 7365-74-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,3,6 and 5 respectively; the second part has 2 digits, 7 and 4 respectively. Calculate Digit Verification of CAS Registry Number 7365-74: (6*7)+(5*3)+(4*6)+(3*5)+(2*7)+(1*4)=114 114 % 10 = 4 So 7365-74-4 is a valid CAS Registry Number.
