67093-27-0 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 67093-27-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,7,0,9 and 3 respectively; the second part has 2 digits, 2 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 67093-27:
(7*6)+(6*7)+(5*0)+(4*9)+(3*3)+(2*2)+(1*7)=140
140 % 10 = 0
So 67093-27-0 is a valid CAS Registry Number.

Dendritic poly(benzyl ether)-b-poly(N-vinylcaprolactam) block copolymers: Self-organization in aqueous media, thermoresponsiveness and biocompatibility

Tang, Gang,Hu, Minqi,He, Fuxi,You, Dan,Qian, Yangyang,Bi, Yunmei

, p. 300 - 308 (2017/12/26)

Four generations of new amphiphilic thermoresponsive linear-dendritic block copolymers (LDBCs) with a linear poly(N-vinylcaprolactam) (PNVCL) block and a dendritic poly(benzyl ether) block are synthesized by atom transfer radical polymerization (ATRP) of N-vinylcaprolactam (NVCL) using dendritic poly(benzyl ether) chlorides as initiators. The copolymers have been characterized by 1H NMR, FTIR, and GPC showing controlled molecular weight and narrow molecular weight distribution (PDI ≤ 1.25). Their self-organization in aqueous media and thermoresponsive property are highly dependent on the generation of dendritic poly(benzyl ether) block. It is observed for the LDBCs that the self-assembled morphology changes from irregularly spherical micelles, vesicles, rod-like large compound vesicles (LCVs), to the coexistence of spherical micelles and rod-like LCVs, as the generation of the dendritic poly(benzyl ether) increases. The results of a cytotoxicity study using an MTT assay method with L929 cells show that the LDBCs are biocompatible.

Synthesis of Curvulone B Using the 2-Chlorobenzyl Protecting Group

Bates, Roderick W.,Wang, Kongchen,Zhou, Guanying,Kang, Dave Zhihong

, p. 751 - 754 (2015/03/30)

A total synthesis of curvulone B has been completed using a Friedel-Crafts reaction and a highly cis-selective intramolecular oxa-Michael addition. The 2-chlorobenzyl protecting group was employed and found to have much greater Lewis acid stability compared to the simple benzyl group.

Supramolecular design for two-component hydrogels with intrinsic emission in the visible region

Rajamalli,Atta, Supriya,Maity, Sandeepan,Prasad, Edamana

, p. 1744 - 1746 (2013/03/14)

We report, for the first time, an in situ formation of two-component hydrogels from pyridine derivatives of poly(aryl ether) dendrons and tartaric acid. The two-component system (dendron + acid) undergoes J-type aggregation, leading to fibrillar type self-assembly in THF-water mixture along with blue (470 nm) and green (500 nm) intrinsic emissions.
