5-Phenyl-1,2,3,4-tetrachlor-5-brom-7,7-dimethoxy-norbornen-2 is a complex organic compound with a unique molecular structure. It consists of a norbornen-2 core, which is a type of bicyclic compound with a seven-membered ring fused to a cyclopropane ring. The molecule is characterized by the presence of a phenyl group (C6H5) attached to the norbornen-2 core, as well as four chlorine atoms (Cl) and one bromine atom (Br) substituting various carbon atoms in the molecule. Additionally, two methoxy groups (-OCH3) are attached to the 7,7-positions of the norbornen-2 core. 5-Phenyl-1,2,3,4-tetrachlor-5-brom-7,7-dimethoxy-norbornen-2 is likely to be of interest in the field of organic chemistry, potentially for its unique properties or as a precursor in the synthesis of other complex molecules.
The CAS Registry Mumber 1158-45-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,1,5 and 8 respectively; the second part has 2 digits, 4 and 5 respectively. Calculate Digit Verification of CAS Registry Number 1158-45: (6*1)+(5*1)+(4*5)+(3*8)+(2*4)+(1*5)=68 68 % 10 = 8 So 1158-45-8 is a valid CAS Registry Number.
