Check Digit Verification of cas no

The CAS Registry Mumber 1403756-48-8 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,0,3,7,5 and 6 respectively; the second part has 2 digits, 4 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1403756-48:
(9*1)+(8*4)+(7*0)+(6*3)+(5*7)+(4*5)+(3*6)+(2*4)+(1*8)=148
148 % 10 = 8
So 1403756-48-8 is a valid CAS Registry Number.

Effect of photoisomerization on the electroactivity and electrochromic behavior of aniline pentamer-based polymers with azo chromophore as reversibly switchable pendant group

By an oxidative coupling polymerization approach, we have synthesized an electroactive polymer with good solubility containing alternating phenyl-capped aniline pentamer in the main chain and azo chromophores in the side chain. In this study, we present reversible example of photochemically induced switching of electroactivity by performing electrochemical CV in two ways: (i) in that the photochemical reaction switch can be photochemically reverted by reirradiation at a different wavelength (ii) in that a photoreaction is used that is thermally reversible. At the same time, electrochemical investigations of electrochromic properties of an aniline-pentamer-based electroactive poly(azine-azo) (EPAA) coating prepared by oxidative coupling polymerization are presented. The in-situ chemical oxidation of the reduced form of soluble, electroactive poly(azine-azo) (EPAA) in N-methyl-2-pyrrolidone (NMP) was monitored by UV-Visible absorption spectra. Moreover, the electrochromic performance of EPAA was investigated by measuring electrochromic photographs and UV absorption spectra.
