1068432-28-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 1068432-28-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,6,8,4,3 and 2 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1068432-28:
(9*1)+(8*0)+(7*6)+(6*8)+(5*4)+(4*3)+(3*2)+(2*2)+(1*8)=149
149 % 10 = 9
So 1068432-28-9 is a valid CAS Registry Number.

Patterned recognition of amines and ammonium ions by a stimuli-responsive foldamer-based hexameric oligophenol host

Sun, Chang,Ren, Changliang,Wei, Yuchen,Qin, Bo,Zeng, Huaqiang

, p. 5307 - 5309 (2013/06/27)

A stimuli-responsive hexameric oligophenol host undergoes amine-induced co-operative folding from a more fluorescent, more linear structure into less fluorescent, more curved or helically folded states, enabling easy identification and classification of the bound amine guests. The Royal Society of Chemistry 2013.

Persistently folded circular aromatic amide pentamers containing modularly tunable cation-binding cavities with high ion selectivity

Qin, Bo,Ren, Changliang,Ye, Ruijuan,Sun, Chang,Chiad, Khalid,Chen, Xiuying,Li, Zhao,Xue, Feng,Su, Haibin,Chass, Gregory A.,Zeng, Huaqiang

supporting information; experimental part, p. 9564 - 9566 (2010/09/03)

In this work, we illustrated a novel design strategy that allows systematically tunable interior properties (effective cavity size, steric crowdedness, and hydrophobicity) contained within a novel class of shape-persistent aromatic pentamers to take place on a scale below 3 A. Such finely tunable structural features are complimented by experimentally observable functional variations in ion-binding potential. Results of the selective, differential binding affinities of three circular pentamers for Li+, Na+, K+, Rb+, and Cs +, substantiated by metal-containing crystal structures and computational modeling, are detailed.

Crystallographic evidence of an unusual, pentagon-shaped folding pattern in a circular aromatic pentamer

Qin, Bo,Chen, Xiuying,Fang, Xiao,Shu, Yingying,Yip, Yeow Kwan,Yan, Yan,Pan, Siyan,Ong, Wei Qiang,Ren, Changliang,Su, Haibin,Zeng, Huaqiang

supporting information; experimental part, p. 5127 - 5130 (2009/05/30)

(Figure Presented) Introduction of a continuous hydrogen-bonding network suppressed the conformational flexibility of an oligomeric backbone. Cyclization of a rigidified, suitably sized oligomer led to a circular aromatic pentamer. Its crystal structure d
