Check Digit Verification of cas no

The CAS Registry Mumber 1380491-91-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,8,0,4,9 and 1 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1380491-91:
(9*1)+(8*3)+(7*8)+(6*0)+(5*4)+(4*9)+(3*1)+(2*9)+(1*1)=167
167 % 10 = 7
So 1380491-91-7 is a valid CAS Registry Number.

Design, syntheses and photochromic properties of dithienylcyclopentene optical molecular switches

Yu, Chuanming,Hu, Bingcheng,Liu, Cheng,Li, Jiting

, (2017)

A kind of basal diarylethene through an easy synthetic procedure was synthesized and characterized, and a Suzuki coupling reaction was frequently operated to obtain the diarylethenes derivatives with some vivid functional groups like bromo, amido and pyridine. Two methods for derivatives of these switches contain porphyrins were described. All of their spectroscopic and photochromic properties were studied and intercompared. It is indicated that the difference in electron densities of the π-conjugated system of the closed forms has effects upon the absorption maxima in visible region of UV–Vis spectra. Dithienylcyclopentenes linked to porphyrins could emit luminescence substantially that display potentials to be used in the applications of nondestructive readout upon binary data storage and smart materials.
