48138-74-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 48138-74-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,8,1,3 and 8 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 48138-74:
(7*4)+(6*8)+(5*1)+(4*3)+(3*8)+(2*7)+(1*4)=135
135 % 10 = 5
So 48138-74-5 is a valid CAS Registry Number.

A robust microporous metal-organic framework constructed from a flexible organic linker for highly selective sorption of methanol over ethanol and water

Huang, Qian,Cai, Jianfeng,Wu, Hui,He, Yabing,Chen, Banglin,Qian, Guodong

experimental part, p. 10352 - 10355 (2012/08/27)

A microporous metal-organic framework MOF 1 [Zn(L)2(methanol) 2] (H2L = (1R,3S)-1,2,2-trimethyl-3-(pyridin-4- ylcarbamoyl)cyclopentanecarboxylic acid) constructed from a flexible Zn 2+ node and a flexible organic linker L was obtained by solvothermal reaction of diamond topology, and exhibits highly selective sorption of methanol over ethanol and water.

Two chiral nonlinear optical coordination networks based on interwoven two-dimensional square grids of double helices

Huang, Qian,Yu, Jiancan,Gao, Junkuo,Rao, Xingtang,Yang, Xiuli,Cui, Yuanjing,Wu, Chuande,Zhang, Zhangjing,Xiang, Shengchang,Chen, Banglin,Qian, Guodong

scheme or table, p. 5291 - 5296 (2011/10/12)

Two new chiral two-dimensional coordination networks, ZnL 2(H2O)2 (1) and CdL2(H 2O)2 (2) [L = 1,2,2-trimethyl-3-(pyridin-4-ylcarbamoyl) cyclopentanecarboxylic acid], have been synthesized and structurally characterized by single X-ray structure analysis, featuring very unusual interwoven (4,4) square grids of double helices. The frameworks exhibit high thermal stability as confirmed by thermogravimetric analysis and powder X-ray diffraction studies. The unique chiral networks attributed to the chiral organic linker have led to their nonlinear optical properties.

Chiral carboxylic acid ligands derived from camphoric acid

Moloney, Mark G.,Paul, Diana R.,Thompson, Russell M.,Wright, Emma

, p. 2551 - 2562 (2007/10/03)

Versatile and convenient preparations of chiral carboxylic acid ligands, derived from camphoric acid, are described, either by esterification of camphoric dichloride or by a regioselective opening of the corresponding anhydride by a variety of alcohols or diols.
