2-endo-4,5,6,7,8,8-Heptachlor-4,7-methano-3a,4,7,7a-tetrahydro-indan, also known as γ-Dihydro-heptachlor, is a complex organic compound with the molecular formula C10H5Cl7. It is a structurally modified derivative of heptachlor, an organochlorine pesticide. 2-endo-4,5,6,7,8,8-Heptachlor-4,7-methano-3a,4,7,7a-tetrahydro-indan, γ-Dihydro-heptachlor features a unique arrangement of seven chlorine atoms and a cyclopentane ring fused to an indane core. It is characterized by its endo configuration at the 2-position and a tetrahydro structure, which distinguishes it from other heptachlor derivatives. γ-Dihydro-heptachlor has been studied for its potential environmental and health impacts, given its persistence and bioaccumulation properties. However, due to its toxic nature and the ban on heptachlor, research and applications of 2-endo-4,5,6,7,8,8-Heptachlor-4,7-methano-3a,4,7,7a-tetrahydro-indan, γ-Dihydro-heptachlor are limited, focusing primarily on understanding its behavior in the environment and its implications for human health.

Check Digit Verification of cas no

The CAS Registry Mumber 5103-62-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,1,0 and 3 respectively; the second part has 2 digits, 6 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 5103-62:
(6*5)+(5*1)+(4*0)+(3*3)+(2*6)+(1*2)=58
58 % 10 = 8
So 5103-62-8 is a valid CAS Registry Number.

Role of water traces in the liquid-phase catalytic hydrochlorination of olefins in organic solvents

Mal'kov,Romm,Abronin

, p. 243 - 246 (2007/11/27)

The liquid-phase hydrochlorination of 4,5,6,7,8,8,-hexachloro-3′,4,7,7′-tetrahydro-4,7-methanoindene (Chlordene) catalyzed by gallium or aluminum halides occurs in the presence of water traces in an aprotic organic solvent. Complexes H2O · M2X6, where M is metal and X is halogen, catalyze this reaction. The reaction proceeds under homogeneous conditions. Under heterogeneous catalytic conditions, the solid phase in the AlCl3-CCl4 system attains the required concentration of AlCl3 in the solution. It was shown using quantum-chemical PM3 calculations that the water molecule facilitates the transfer of proton in the form of the hydroxonium ion from an HCl molecule to olefin.
