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.

Visual detection of fluoride ions

-

Page/Page column 25-26, (2015/12/18)

Dendrimer-hydrazides are coupled to polycyclic aromatic hydrocarbons for use in the visual detection of the presence of low levels of fluoride in a sample. The dendrimers can have a phenyl core, a first generation of aralkyl ethers, and an optional second generation of aralkyl ethers. The compounds form gels with solvents. In the presence of fluoride ion, the gels undergo color changes and/or gel to liquid phase change.

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

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

supporting information, 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.
