Check Digit Verification of cas no

The CAS Registry Mumber 1263093-69-1 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,6,3,0,9 and 3 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1263093-69:
(9*1)+(8*2)+(7*6)+(6*3)+(5*0)+(4*9)+(3*3)+(2*6)+(1*9)=151
151 % 10 = 1
So 1263093-69-1 is a valid CAS Registry Number.

Oligofluorene blue emitters for cholesteric liquid crystal lasers

Chinelatto Jr.,del Barrio,Pi?ol,Oriol,Matranga,De Santo,Barberi

, p. 130 - 139 (2010)

We present the synthesis and characterization of an oligofluorene series whose chemical structure has been tuned to have amorphous nature, compatibility with liquid crystalline matrices and intrinsic chirality. Oligofluorenes are good blue emitters and the emission quantum yield is around 0.8 in the violet-blue range. The prepared materials are suitable for mirror-less laser applications based on a dye-doped liquid crystal resonator. We propose to use fluorene-based compounds to combine two necessary properties to achieve laser emission from cholesteric liquid crystal mixtures: chirality and luminescence. A good intensity emission and a fine tuning of the laser emission are demonstrated.
