127266-02-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 127266-02-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,7,2,6 and 6 respectively; the second part has 2 digits, 0 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 127266-02:
(8*1)+(7*2)+(6*7)+(5*2)+(4*6)+(3*6)+(2*0)+(1*2)=118
118 % 10 = 8
So 127266-02-8 is a valid CAS Registry Number.

Optimizing the photochromic performance of naphthopyrans in a rigid host matrix using poly(dimethylsiloxane) conjugation

Ercole, Francesca,Malic, Nino,Davis, Thomas P.,Evans, Richard A.

scheme or table, p. 5612 - 5623 (2010/07/05)

A series of methoxy substituted 2,2-diaryl-2H-naphthopyran photochromic dyes were assembled incorporating hydroxy functionality to allow their subsequent attachment to flexible poly(dimethylsiloxane) oligomers. The photochromic performance of the generated PDMS-naphthopyran conjugates was studied in a thermoset host matrix and compared to non-conjugated, electronically equivalent control dyes. Both coloration and decoloration speeds were found to be greatly improved with critical T1/2 decoloration times reduced by 42-80%. The extent of solution-like performance provided by PDMS conjugation in the rigid host was examined with reference to the fade performance of control dyes in solution, and found to range from 20 to 90%. These measures are believed to be influenced by the electronic nature and steric interactions of the photochromic dyes.
