909389-74-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 909389-74-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,0,9,3,8 and 9 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 909389-74:
(8*9)+(7*0)+(6*9)+(5*3)+(4*8)+(3*9)+(2*7)+(1*4)=218
218 % 10 = 8
So 909389-74-8 is a valid CAS Registry Number.

Molecular architecture via coordination: Self-assembly of nanoscale hexagonal metallodendrimers with designed building blocks

Yang, Hai-Bo,Das, Neeladri,Huang, Feihe,Hawkridge, Adam M.,Muddiman, David C.,Stang, Peter J.

, p. 10014 - 10015 (2006)

The first self-assembly of nanoscale metallodendrimers that have a hexagonal cavity as a core via the directional-bonding approach is reported. All metallodendrimers were characterized by multinuclear NMR (1H and 31P), mass spectrome

Orthogonal Self-Assembly of a Two-Step Fluorescence-Resonance Energy Transfer System with Improved Photosensitization Efficiency and Photooxidation Activity

Jia, Pei-Pei,Xu, Lin,Hu, Yi-Xiong,Li, Wei-Jian,Wang, Xu-Qing,Ling, Qing-Hui,Shi, Xueliang,Yin, Guang-Qiang,Li, Xiaopeng,Sun, Haitao,Jiang, Yanrong,Yang, Hai-Bo

supporting information, p. 399 - 408 (2021/01/12)

During the past few decades, fabrication of multistep fluorescence-resonance energy transfer (FRET) systems has become one of the most attractive topics within supramolecular chemistry, chemical biology, and materials science. However, it is challenging t

Protection of COOH and OH groups in acid, base and salt free reactions

Zhu, Xiaotao,Qian, Bo,Wei, Rongbiao,Huang, Jian-Dong,Bao, Hongli

supporting information, p. 1444 - 1447 (2018/04/12)

We report an iron-catalyzed general functional group protection method with inexpensive reagents. This environmentally benign process does not use acids or bases, and does not produce waste products. Further purification beyond filtration and evaporation is, in most cases, unnecessary. Free COOH and OH groups can be protected in a one-pot reaction.

Ligand-Promoted Palladium-Catalyzed C?H Acetoxylation of Simple Arenes

Valderas, Carolina,Naksomboon, Kananat,Fernández-Ibá?ez, M. ángeles

, p. 3213 - 3217 (2016/10/24)

The palladium-catalyzed C?H oxidation of simple arenes is an attractive strategy to obtain phenols, which have many applications in the fine chemicals industry. Although some advances have been made in this research area, low reactivity and selectivity are, in general, observed. This report describes a new catalytic system for the efficient C?H acetoxylation of simple arenes based on Pd(OAc)2 and a pyridinecarboxylic acid ligand.
