205885-18-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 205885-18-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,5,8,8 and 5 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 205885-18:
(8*2)+(7*0)+(6*5)+(5*8)+(4*8)+(3*5)+(2*1)+(1*8)=143
143 % 10 = 3
So 205885-18-3 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
