99059-33-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 99059-33-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,9,0,5 and 9 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 99059-33:
(7*9)+(6*9)+(5*0)+(4*5)+(3*9)+(2*3)+(1*3)=173
173 % 10 = 3
So 99059-33-3 is a valid CAS Registry Number.

Synthesis of Chiral C2-Symmetric Binucleating Ligands
Fahrni, Christoph J.,Pfaltz, Andreas
, p. 491 - 506 (2007/10/03)
The synthesis of a series of chiral enantiomerically pure C2-symmetric binucleating ligands is reported. Ligands of type 1-4, which consist of a phenolic or heterocyclic unit bridging two chiral dihydrooxazole rings, are readily accessible from
