2694-25-9 Usage
General Description
The chemical compound "(1,4,5,6,7,7-hexachlorobicyclo[2.2.1]hepta-2,5-diene-2,3-diyl)dimethanol" is a highly chlorinated organic compound that contains a bicyclic ring structure. It is a diol, meaning it contains two hydroxyl (OH) groups, and is derived from the degradation of pesticides such as endosulfan. (1,4,5,6,7,7-hexachlorobicyclo[2.2.1]hepta-2,5-diene-2,3-diyl)dimethanol is known to be persistent in the environment and has been found to bioaccumulate in organisms. It is also toxic to aquatic organisms and is a potential pollutant of concern due to its environmental persistence and toxicity. The chemical's exact properties and uses are not widely documented, but its chlorinated structure suggests it may have been used as a pesticide or industrial chemical in the past.
Check Digit Verification of cas no
The CAS Registry Mumber 2694-25-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,6,9 and 4 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 2694-25:
(6*2)+(5*6)+(4*9)+(3*4)+(2*2)+(1*5)=99
99 % 10 = 9
So 2694-25-9 is a valid CAS Registry Number.

Enzymatic desymmetrization of meso-2,3-bis(acetoxymethyl) and bis(hydroxymethyl) substituted hexachloronorbornadiene derivatives
Tanyeli, Cihangir,Karadag, Timur,Akhmedov, Idris Mecitoglu
, p. 307 - 310 (2004)
meso-Bis(acetoxymethyl)-1,4,5,6,7,7-hexachlorobicyclo[2.2.1]hepta-2, 5-diene and meso-bis(hydroxymethyl)-1,4,5,6,7,7-hexachlorobicyclo[2.2.1]hepta-2, 5-diene were transformed into chiral monoesters with 65-92% ee via enzymatic desymmetrization using various lipases. The absolute configuration was determined by transforming 2-acetoxymethyl-3-hydroxymethyl-1,4,5,6,7,7- hexachlorobicyclo[2.2.1]hepta-2,5-diene into the 2-acetoxymethyl-3- hydroxymethylbicyclo[2.2.1]hepta-2,5-diene of known absolute configuration.
