The chemical "9r.10c-bis-(4-fluoro-phenyl)-9.10-dihydro-phenanthrenediol-(9.10t)" is a complex organic compound with a unique molecular structure. It features a phenanthrene core, which is a tricyclic aromatic hydrocarbon, with two hydroxyl groups at the 9 and 10 positions. The molecule is further characterized by the presence of two 4-fluoro-phenyl groups attached at the 9 and 10 positions, which introduces fluorine atoms into the structure. This fluorination can significantly alter the chemical and physical properties of the compound, such as its reactivity, lipophilicity, and potential biological activity. The "dihydro" prefix indicates that the compound has two fewer hydrogen atoms than the fully unsaturated phenanthrene, suggesting a reduction in the molecule has occurred. The "9.10t" notation likely refers to the specific torsion or spatial arrangement of the molecule around the 9-10 bond, which can influence its stereochemistry. Overall, 9r.10c-bis-(4-fluoro-phenyl)-9.10-dihydro-phenanthrenediol-(9.10t) represents a specialized area of organic chemistry, potentially with applications in materials science, pharmaceuticals, or as a precursor in the synthesis of more complex molecules.
The CAS Registry Mumber 424-83-9 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 4,2 and 4 respectively; the second part has 2 digits, 8 and 3 respectively. Calculate Digit Verification of CAS Registry Number 424-83: (5*4)+(4*2)+(3*4)+(2*8)+(1*3)=59 59 % 10 = 9 So 424-83-9 is a valid CAS Registry Number.
