Check Digit Verification of cas no
The CAS Registry Mumber 70964-44-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,0,9,6 and 4 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 70964-44:
(7*7)+(6*0)+(5*9)+(4*6)+(3*4)+(2*4)+(1*4)=142
142 % 10 = 2
So 70964-44-2 is a valid CAS Registry Number.

Chiral phosphinopyrrolidine compounds and their use for asymmetric synthesis of optically active compounds
-
, (2008/06/13)
New chiral phosphinopyrrolidine compounds of the general formula: STR1 wherein R1 is a hydrogen atom, --COR, --COOR, --CONHR or --SO2 --R where R is an alkyl or aryl group, R2 and R3 each represents independently an aryl group which may have a substituent or substituents, and R4 and R5 each represents independently an aliphatic or cycloaliphatic hydrocarbyl group which may have a substituent or substituents, as well as the use of these compounds as ligand for a metal complex catalyst for asymmetric synthesis of optically active compounds. The new chiral phosphinopyrrolidine compounds are useful ligands which attain both of high optical yield and high reaction efficiency in catalytic asymmetric reduction.
