General Description
(S)-(-)-2-(Diphenylphosphoryl)-2'-ethyl-1,1'-binaphthyl, also known as (S)-(-)-DPPBIN, is an organophosphorus compound and chiral ligand that is commonly used in asymmetric synthesis and catalysis. As a chiral ligand, it can selectively bind to metal centers in catalytic reactions, facilitating the formation of enantioselective products. Due to its unique structure and properties, (S)-(-)-DPPBIN has been used in various asymmetric reactions, including hydrogenation, allylation, and addition reactions, to efficiently generate chiral compounds with high enantiomeric purity. Its versatility and efficiency make it a valuable tool in the development of pharmaceuticals, agrochemicals, and fine chemicals.
Check Digit Verification of cas no
The CAS Registry Mumber 137769-29-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,7,7,6 and 9 respectively; the second part has 2 digits, 2 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 137769-29:
(8*1)+(7*3)+(6*7)+(5*7)+(4*6)+(3*9)+(2*2)+(1*9)=170
170 % 10 = 0
So 137769-29-0 is a valid CAS Registry Number.
