618428-22-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 618428-22-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,1,8,4,2 and 8 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 618428-22:
(8*6)+(7*1)+(6*8)+(5*4)+(4*2)+(3*8)+(2*2)+(1*2)=161
161 % 10 = 1
So 618428-22-1 is a valid CAS Registry Number.

Electronic absorption and emission properties of bishydrazone [2?×?2] metallosupramolecular grid-type architectures

Holub, Jan,Santoro, Antonio,Lehn, Jean-Marie

, p. 223 - 231 (2019)

Several ditopic ligands containing two tridentate bishydrazone coordination subunits and their Zn(II) and Cd(II) [2 × 2] grid-type complexes were prepared and their photoluminescent properties studied. A special attention was devoted to the influence of the orientation of the hydrazone group N–N[dbnd]in the core of the ligands and their complexes. Its reversal from [pyridine[dbnd]N–N–pyrimidine] (L1) to [pyridine–N–N[dbnd]pyrimidine] (L2) has a strong impact on the observed absorption and emission behaviour of particular ligands (L1 and L2) as well as of their [2 × 2] grid assemblies. The further lateral functionalization of the ligands led to different emission quantum yields of the resulting grids, while their emission and absorption spectra varied very little. The simplest derivative L1 turned out to have the best performance with, for its Zn(II) complex, relatively high quantum yield 60%.

Generation of dynamic constitutional diversity and driven evolution in helical molecular strands under Lewis acid catalyzed component exchange

Giuseppone, Nicolas,Schmitt, Jean-Louis,Lehn, Jean-Marie

, p. 4902 - 4906 (2007/10/03)

A stir in the library: The efficient Sc(OTf)3-catalyzed transimination of helical oligo-hydrazone strands has been utilized to yield a highly diverse constitutional dynamic library through assembly, dissociation, and exchange of components. Thi
