1-fluoro-2,4,6-triphenyl-1-p-tolyl-1λ5-phosphinine is a complex organic compound that belongs to the class of phosphinine derivatives. It is characterized by the presence of a phosphorus atom in a five-membered ring structure, with a fluorine atom at the 1-position, three phenyl groups at the 2, 4, and 6 positions, and a p-tolyl group (a tolyl group with a para-methyl substitution) at the 1-position. 1-fluoro-2,4,6-triphenyl-1-p-tolyl-1λ5-phosphinine is of interest in the field of organophosphorus chemistry due to its unique structure and potential applications in materials science and medicinal chemistry. The synthesis and properties of such compounds are often studied to understand their reactivity and to explore their potential as precursors for more complex molecules or as active ingredients in pharmaceuticals.
The CAS Registry Mumber 40425-20-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,0,4,2 and 5 respectively; the second part has 2 digits, 2 and 0 respectively. Calculate Digit Verification of CAS Registry Number 40425-20: (7*4)+(6*0)+(5*4)+(4*2)+(3*5)+(2*2)+(1*0)=75 75 % 10 = 5 So 40425-20-5 is a valid CAS Registry Number.
