"7,7,16,16-Tetraphenyl-5,6,7,8,9,14,15,16,17,18-decahydro-7,16-distanna-dibenzo[a,h]cyclotetradecene" is a complex organometallic compound characterized by its unique structure. It features a cyclotetradecene ring system, which is a 14-membered cyclic hydrocarbon, with two benzene rings fused to it, forming a dibenzo[a,h] structure. The compound is further distinguished by the presence of two phenyl groups (C6H5) attached to the 7th and 16th carbon atoms, and two tin atoms bridging the 7th and 16th carbon atoms, creating a distanna structure. The "decahydro" prefix indicates the presence of ten hydrogen atoms in the molecule, which are part of the cycloalkane ring. 7,7,16,16-Tetraphenyl-5,6,7,8,9,14,15,16,17,18-decahydro-7,16-distanna-dibenzo[a,h]cyclotetradecene is of interest in the field of organometallic chemistry, potentially for its electronic properties or as a precursor in the synthesis of other complex organometallic compounds.
The CAS Registry Mumber 3855-91-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,8,5 and 5 respectively; the second part has 2 digits, 9 and 1 respectively. Calculate Digit Verification of CAS Registry Number 3855-91: (6*3)+(5*8)+(4*5)+(3*5)+(2*9)+(1*1)=112 112 % 10 = 2 So 3855-91-2 is a valid CAS Registry Number.
