2-(Fluorenyl-9-yl)-diphenylmethan, also known as 2-(9H-fluoren-9-yl)-1,1-diphenylethanone, is an organic compound characterized by its unique molecular structure. It features a fluorenyl group (a derivative of fluorene) at the 2-position, which is a polycyclic aromatic hydrocarbon with a structure similar to that of naphthalene but with an additional six-membered ring. The molecule also includes two phenyl groups attached to a central carbon atom, forming a diphenylmethane structure. 2-(Fluorenyl-(9))-diphenylmethan is often used in the synthesis of various organic compounds and materials due to its stability and the presence of the fluorenyl group, which can participate in a range of chemical reactions. Its applications may span across different fields, including pharmaceuticals, materials science, and the creation of advanced organic materials.
The CAS Registry Mumber 2116-38-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,1,1 and 6 respectively; the second part has 2 digits, 3 and 8 respectively. Calculate Digit Verification of CAS Registry Number 2116-38: (6*2)+(5*1)+(4*1)+(3*6)+(2*3)+(1*8)=53 53 % 10 = 3 So 2116-38-3 is a valid CAS Registry Number.
