Bis(triphenylphosphine)iminium chloride, also known as [Ph3P=NPPh3]Cl, is a phosphorus-containing organic compound that serves as a versatile reagent in organic synthesis. It is formed by the reaction of triphenylphosphine with a halogenated nitrogen source, resulting in a cationic iminium species. bis(triphenylphosphine)iminiumhloride is widely used as a catalyst or a ligand in various chemical transformations, such as C-C bond formations, cyclizations, and oxidation reactions. Its stability, ease of synthesis, and ability to form strong π-π interactions with aromatic substrates make it a valuable tool in the field of catalysis and organophosphorus chemistry.

Check Digit Verification of cas no

The CAS Registry Mumber 2156-68-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,1,5 and 6 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 2156-68:
(6*2)+(5*1)+(4*5)+(3*6)+(2*6)+(1*8)=75
75 % 10 = 5
So 2156-68-5 is a valid CAS Registry Number.
