4963-43-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 4963-43-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,9,6 and 3 respectively; the second part has 2 digits, 4 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 4963-43:
(6*4)+(5*9)+(4*6)+(3*3)+(2*4)+(1*3)=113
113 % 10 = 3
So 4963-43-3 is a valid CAS Registry Number.

Comparative Evaluation of Substituent Effect on the Photochromic Properties of Spiropyrans and Spirooxazines

Balmond, Edward I.,Tautges, Brandon K.,Faulkner, Andrea L.,Or, Victor W.,Hodur, Blanka M.,Shaw, Jared T.,Louie, Angelique Y.

Spiropyrans and spirooxazines represent an important class of photochromic compounds with a wide variety of applications. In order to effectively utilize and design these photoswitches it is desirable to understand how the substituents affect photochromic properties, and how the different structural motifs compare under identical conditions. In this work a small library of photoswitches was synthesized in order to comparatively evaluate the effect of substituent modifications and structure on photochromism. The library was designed to modify positions that were believed to have the greatest effect on C-O bond lability and therefore the photochromic properties. Herein we report a comparative analysis of the UV and visible light responses of 30 spiropyrans, spiroindolinonaphthopyrans, and spirooxazines. The influence of gadolinium(III) binding was also investigated on the library of compounds to determine its effect on photoswitching. Both assays demonstrated different trends in substituent and structural requirements for optimal photochromism.

SYNTHESE DE QUELQUES SPIRO ET SPIRO PHOTOCHROMIQUES. APPLICATION DE LA METHODOLOGIE DE LA RECHERCHE EXPERIMENTALE

Pottier, E.,Sergent, M.,Luu, R. Phan Tan,Guglielmetti, R.

, p. 719 - 740 (2007/10/02)

Some spiro I and spiro II substituted by different groups were synthesized in order to evaluate their photochromic properties and to optimize the preparation of spiroheterocyclic systems.In addition, some spiro III were also prepared as reference compounds.Their physical and spectroscopic characteristics (UV, 1H and 13C) were determined.A study using the experimental design methodology allowed to point out the most important factors for improving the reaction yields. KEYWORDS: Photochromism, spirooxazines, spiropyrans, synthesis, 1H NMR, experimental design methodology.
