Triphenyl[1-(2-propenyl)-2-(phenylphenacylidenehydrazono)propyl]phosphonium bromide is a complex organic compound with the chemical formula C33H34BrN2OP. It is a phosphonium salt, characterized by the presence of a phosphonium cation (P+) bonded to three phenyl groups and a complex organic ligand. The ligand consists of a propyl chain with a 2-propenyl group at the first carbon, and a phenylphenacylidenehydrazono group at the second carbon. triphenyl<1-(2-propenyl)-2-(phenylphenacylidenehydrazono)propyl>phosphonium bromide is typically used in organic synthesis and as a reagent in various chemical reactions due to its unique structure and properties. It is soluble in organic solvents and can be synthesized through a series of chemical reactions involving phosphorus, bromine, and the appropriate organic precursors.

Check Digit Verification of cas no

The CAS Registry Mumber 81724-89-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,1,7,2 and 4 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 81724-89:
(7*8)+(6*1)+(5*7)+(4*2)+(3*4)+(2*8)+(1*9)=142
142 % 10 = 2
So 81724-89-2 is a valid CAS Registry Number.
