Check Digit Verification of cas no

The CAS Registry Mumber 2523-42-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,5,2 and 3 respectively; the second part has 2 digits, 4 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 2523-42:
(6*2)+(5*5)+(4*2)+(3*3)+(2*4)+(1*2)=64
64 % 10 = 4
So 2523-42-4 is a valid CAS Registry Number.

Polyphenol derivatives of porphyrins containing fluorene units: Synthesis and positive-tone photoresists for 22-nanometer lithography

Vainer, A. Ya.,Dyumaev,Kovalenko,Babuskin, Ya. L.,Krichevskaya,Lubenskii

, p. 174 - 178 (2016)

A new strategy was proposed for the synthesis of polyphenol derivatives of fluorene-containing porphyrins to be used as the base for positive-tone photoresists for lithography with exposure at 13.5 nm wavelength, which allow fabrication of microchips with a size of down to 22 nm. Polyphenols based on fluorenecontaining porphyrins were synthesized for the first time. It was shown that these polyphenol derivatives can be used to obtain positive-tone photoresists with a resolution of 22 nm.

An investigation of the effect of conjugation on fluorene based chromophores; Optoelectronic and electrochemical behavior

Mahar, Jamaluddin,Saeed, Aamer,Belfield, Kevin D.,Iqbal, Anila,Irfan, Madiha,Shabir, Ghulam,Larik, Fayaz Ali,Channar, Pervaiz Ali

, p. 385 - 392 (2017)

The requisition of small light emitting organic molecules is on the rise in the field of organic electronics. This study is aimed at synthesis of fluorene based chromophores which possess promising optoelectronic properties. The characterization of synthesized derivatives was carried out by spectroscopy (1H-NMR and 13C-NMR) and spectrometry (EI-MS). The optical properties evaluated by using UV-Vis spectroscopy, were from 394 to 420 nm, Fluorescence ranged 48 nm-113 nm, HOMO energy levels are ?6.75 eV to ?7.15 eV LUMO -4.08 to ?4.52eV with a band gap energy values 2.63–2.67 eV. The band gap energy values suggest that these synthesized molecules can be manipulated in the designing of blue and green OLEDS.

Solid-state construction of zigzag periphery: Via intramolecular C-H insertion induced by alumina-mediated C-F activation

Akhmetov, Vladimir,Amsharov, Konstantin,F?rtsch, Andreas,Feofanov, Mikhail

supporting information, p. 12325 - 12328 (2021/11/30)

Caryl-F bond activation has become an important and quickly developing method for construction of carbon-based materials. We report that alumina-mediated C-F bond activation (AmCFA) enables construction of PAHs with zigzag periphery. This method includes
