9,9,9-Triphenyl-9λ5-phosphapentacyclo[4.3.0.02,5.03,8.04,7]nonane is a complex organophosphorus compound with a unique cyclic structure. It consists of a central phosphorus atom bonded to five carbon atoms, forming a nonane ring. The phosphorus atom is in a λ5 (pentahapto) bonding mode, meaning it interacts with five carbon atoms simultaneously. The three phenyl groups are attached to the phosphorus atom, further enhancing the molecule's stability and reactivity. 9,9,9-triphenyl-9lambda~5~-phosphapentacyclo[4.3.0.0~2,5~.0~3,8~.0~4,7~]nonane is of interest in the field of organophosphorus chemistry due to its potential applications in various chemical reactions and as a ligand in coordination chemistry. Its unique structure and properties make it a valuable subject for research and development in the synthesis of new materials and compounds.
The CAS Registry Mumber 30092-40-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,0,0,9 and 2 respectively; the second part has 2 digits, 4 and 0 respectively. Calculate Digit Verification of CAS Registry Number 30092-40: (7*3)+(6*0)+(5*0)+(4*9)+(3*2)+(2*4)+(1*0)=71 71 % 10 = 1 So 30092-40-1 is a valid CAS Registry Number.
