903899-94-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 903899-94-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,0,3,8,9 and 9 respectively; the second part has 2 digits, 9 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 903899-94:
(8*9)+(7*0)+(6*3)+(5*8)+(4*9)+(3*9)+(2*9)+(1*4)=215
215 % 10 = 5
So 903899-94-5 is a valid CAS Registry Number.

PROCESS FOR PREPARING ENANTIOMERICALLY ENRICHED FERROCENYL LIGANDS
-
Page/Page column 25-26, (2010/02/14)
The present invention relates to the preparation of ligands of the type (I), (II) and (III) via a copper-catalyzed three-component coupling. These are preferably used as ligands in reactions catalyzed by transition metals, in which they frequently exert a strong chiral induction.
