29420-81-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 29420-81-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,9,4,2 and 0 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 29420-81:
(7*2)+(6*9)+(5*4)+(4*2)+(3*0)+(2*8)+(1*1)=113
113 % 10 = 3
So 29420-81-3 is a valid CAS Registry Number.

The synthesis and recognition properties of colorimetric fluoride receptors bearing sulfonamide

Shang, Xue-Fang,Lin, Hai,Lin, Hua-Kuan

, p. 530 - 534 (2007)

Two artificial receptors, 1,2-bis-p-substituted phenyl-sulfonamido-4,5-bis-nitrobenzene, have been designed and synthesized. The interactions of these receptors with halide anions are determined by UV-vis and 1H NMR titration experiments. Resul

Singly and Doubly Quinoxaline-Fused BIII Subporphyrins

Kise, Koki,Osuka, Atsuhiro

, p. 15493 - 15497 (2019/11/14)

B-Phenyl BIII subporphyrin-α-diones prepared in a three-step reaction sequence from the parent subporphyrin were condensed with 1,2-diaminobenzenes to give the corresponding quinoxaline-fused subporphyrins in variable yields. Quinoxaline-fused B-phenyl-5,10,15-triphenyl BIII subporphyrin was transformed to the corresponding subporphyrin-α-dione in the same three-step reaction sequence, which was then condensed with 1,2-diaminobenzene to give doubly quinoxaline-fused subporphyrin. These quinoxaline-fused subporphyrins exhibit redshifted absorption and fluorescence spectra compared with the parent one. A singly quinoxaline-fused subporphyrin bearing three meso-bis(4-dimethylaminophenyl)aminophenyl substituents shows blueshifted fluorescence in less polar solvent, which has been ascribed to emission associated with charge recombination of intramolecular charge transfer (CT) state.

Synthesis and photophysics of a red-light absorbing supramolecular chromophore system

Rombouts, Jeroen A.,Ravensbergen, Janneke,Frese, Raoul N.,Kennis, John T. M.,Ehlers, Andreas W.,Slootweg, J. Chris,Ruijter, Eelco,Lammertsma, Koop,Orru, Romano V. A.

, p. 10285 - 10291 (2014/08/18)

In search of supramolecular antenna systems for light-harvesting applications, we report on a short and effective synthesis of a fused NDI-zinc-salphen-based chromophore (salphen = bis-salicylimide phenylene) and its photophysical properties. A supramolec
