156517-64-5 Usage
General Description
(3S,4S)-(-)-1-Benzyl-3,4-bis(diphenylphosphino)pyrrolidine is a chiral ligand used in organic synthesis and catalysis. It consists of a pyrrolidine ring with two diphenylphosphino groups and a benzyl group attached. These types of ligands are often used in transition metal-catalyzed reactions to stabilize metal catalysts and control their reactivity and selectivity. They are commonly used in asymmetric hydrogenation and other enantioselective reactions. This particular compound, being chiral, can influence the stereochemistry of the reactions it is involved in. Its applications include the synthesis of pharmaceuticals, natural products, and other fine chemicals.
Check Digit Verification of cas no
The CAS Registry Mumber 156517-64-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,6,5,1 and 7 respectively; the second part has 2 digits, 6 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 156517-64:
(8*1)+(7*5)+(6*6)+(5*5)+(4*1)+(3*7)+(2*6)+(1*4)=145
145 % 10 = 5
So 156517-64-5 is a valid CAS Registry Number.
