Bicyclo[2.2.1]hept-2-ene, 1,2,3,4,7,7-hexachloro-5-(chloromethyl)-, also known as Hexachloro-5-(chloromethyl)bicyclo[2.2.1]hept-2-ene, is a complex organic compound with the molecular formula C8H5Cl7. It is a halogenated derivative of bicyclo[2.2.1]hept-2-ene, featuring a bicyclic structure with six chlorine atoms and one chloromethyl group. Bicyclo[2.2.1]hept-2-ene,1,2,3,4,7,7-hexachloro- 5-(chloromethyl)- is primarily used as an intermediate in the synthesis of various pesticides and pharmaceuticals, particularly in the production of the insecticide Lindane. Due to its highly chlorinated nature, it may exhibit potential environmental and health concerns, such as persistence in the environment and bioaccumulation in the food chain.
The CAS Registry Mumber 3309-83-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,3,0 and 9 respectively; the second part has 2 digits, 8 and 3 respectively. Calculate Digit Verification of CAS Registry Number 3309-83: (6*3)+(5*3)+(4*0)+(3*9)+(2*8)+(1*3)=79 79 % 10 = 9 So 3309-83-9 is a valid CAS Registry Number.
