Pentaphenyltriphosphane, also known as (C6H5)5P3, is an organophosphorus compound characterized by its unique structure, which consists of three phosphorus atoms connected to each other in a triangular arrangement, with each phosphorus atom bonded to five phenyl groups (C6H5). pentaphenyltriphosphane is of interest in the field of organophosphorus chemistry due to its potential applications in materials science and as a precursor in the synthesis of other phosphorus-containing compounds. It is a white, crystalline solid that is sensitive to air and moisture, and it is typically handled under an inert atmosphere. The compound's stability and reactivity can be influenced by the steric bulk of the phenyl groups, which can affect its electronic properties and its ability to participate in various chemical reactions.

Check Digit Verification of cas no

The CAS Registry Mumber 5748-54-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,7,4 and 8 respectively; the second part has 2 digits, 5 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 5748-54:
(6*5)+(5*7)+(4*4)+(3*8)+(2*5)+(1*4)=119
119 % 10 = 9
So 5748-54-9 is a valid CAS Registry Number.
