143998-20-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 143998-20-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,3,9,9 and 8 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 143998-20:
(8*1)+(7*4)+(6*3)+(5*9)+(4*9)+(3*8)+(2*2)+(1*0)=163
163 % 10 = 3
So 143998-20-3 is a valid CAS Registry Number.

Goldberg Active Template Synthesis of a [2]Rotaxane Ligand for Asymmetric Transition-Metal Catalysis

Hoekman, Steven,Kitching, Matthew O.,Leigh, David A.,Papmeyer, Marcus,Roke, Diederik

, p. 7656 - 7659 (2015)

We report on the active template synthesis of a [2]rotaxane through a Goldberg copper-catalyzed C-N bond forming reaction. A C2-symmetric cyclohexyldiamine macrocycle directs the assembly of the rotaxane, which can subsequently serve as a ligan

Self-assembly, spectroscopic, and electrochemical properties of [n]rotaxanes

Ashton,Ballardini,Balzani,Belohradsky,Gandolfi,Philp,Prodi,Raymo,Reddington,Spencer,Stoddart,Venturi,Williams

, p. 4931 - 4951 (2007/10/03)

Synthetic approaches to self-assembling [n]rotaxanes incorporating Π- electron deficient bipyridinium-based dumbbell-shaped components and Π- electron rich hydroquinone-based macrocycles have been developed. In particular, the so-called slippage methodolo

A New Design Strategy for the Self-assembly of Molecular Shuttles

Ashton, Peter R.,Philp, Douglas,Spencer, Neil,Stoddart, J. Fraser

, p. 1124 - 1128 (2007/10/02)

A strategy for the construction of a rotaxane-comprised of a dumbbell-shaped component containing two ?-electron-deficient 4,4'-bipyridinium units encircled by one ?-electron-rich bisparaphenylene-34-crown-10 macrocycle-by a constitutionally determined
