Tris-(p-chlorphenyl)-fluorenyl-(9)-phosphonium-bromid, also known as 9-(Tris(4-chlorophenyl)phosphonio)fluorene bromide, is a complex organic compound with the chemical formula C36H22BrCl3P. It is a phosphonium salt derived from fluorene, a polycyclic aromatic hydrocarbon, and features three 4-chlorophenyl groups attached to a phosphorus atom. Tris-(p-chlorphenyl)-fluorenyl-⁽⁹⁾-phosphonium-bromid is often used as a reagent in organic synthesis, particularly in the formation of carbon-carbon bonds and as a phase-transfer catalyst. Its bromide counterion makes it a useful precursor in the synthesis of other phosphonium salts and can be used in various applications, including the preparation of conducting polymers and as a ligand in coordination chemistry.

Check Digit Verification of cas no

The CAS Registry Mumber 7293-72-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,2,9 and 3 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 7293-72:
(6*7)+(5*2)+(4*9)+(3*3)+(2*7)+(1*2)=113
113 % 10 = 3
So 7293-72-3 is a valid CAS Registry Number.
