"9-{2-[1-Bromo-meth-(Z)-ylidene]-4,4-diphenyl-but-3-enylidene}-9H-fluorene" is a complex organic compound characterized by its unique molecular structure. It features a fluorene core, which is a derivative of polycyclic aromatic hydrocarbons, with a 9H-fluorene indicating a hydrogenated version of fluorene. The compound is further defined by a but-3-enylidene group, which is a four-carbon chain with a double bond in the third position, attached to the fluorene at the 9-position. This but-3-enylidene group is itself substituted with a 4,4-diphenyl group, indicating two phenyl rings attached to each other, and a 1-bromo-meth-(Z)-ylidene moiety, which introduces a bromine atom and a double bond in the Z configuration. The compound's structure and properties make it a potential candidate for various applications in organic chemistry, such as in the synthesis of pharmaceuticals or materials science, due to its specific electronic and steric characteristics.
The CAS Registry Mumber 4612-66-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,6,1 and 2 respectively; the second part has 2 digits, 6 and 6 respectively. Calculate Digit Verification of CAS Registry Number 4612-66: (6*4)+(5*6)+(4*1)+(3*2)+(2*6)+(1*6)=82 82 % 10 = 2 So 4612-66-2 is a valid CAS Registry Number.
