792921-26-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 792921-26-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 7,9,2,9,2 and 1 respectively; the second part has 2 digits, 2 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 792921-26:
(8*7)+(7*9)+(6*2)+(5*9)+(4*2)+(3*1)+(2*2)+(1*6)=197
197 % 10 = 7
So 792921-26-7 is a valid CAS Registry Number.

Resettable, multi-readout logic gates based on controllably reversible aggregation of gold nanoparticles

Liu, Dingbin,Chen, Wenwen,Sun, Kang,Deng, Ke,Zhang, Wei,Wang, Zhuo,Jiang, Xingyu

, p. 4103 - 4107 (2011/07/07)

A resettable logic system based on spiropyran-modified gold nanoparticles that is capable of AND, OR, and INHIBIT logic operations has been constructed. Several methods can record the output of this process, including the naked eye, UV/Vis spectroscopy, d

Visual detection of copper(II) by azide- and alkyne-functionalized gold nanoparticles using click chemistry

Zhou, Yang,Wang, Shixing,Zhang, Ke,Jiang, Xingyu

supporting information; experimental part, p. 7454 - 7456 (2009/03/12)

(Figure Presented) Just one click, and the color's gone: In the presence of Cu2+ with sodium ascorbate as a reductant, gold nanoparticles that have azide- and alkyne-terminated groups undergo aggregation as the result of CuI-catalyzed click chemistry. This process can be monitored by eye without the aid of instruments (NPs=nanoparticles).
