Check Digit Verification of cas no

The CAS Registry Mumber 136494-09-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,6,4,9 and 4 respectively; the second part has 2 digits, 0 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 136494-09:
(8*1)+(7*3)+(6*6)+(5*4)+(4*9)+(3*4)+(2*0)+(1*9)=142
142 % 10 = 2
So 136494-09-2 is a valid CAS Registry Number.

Synthesis and photophysical properties of fluorescent 2,5- dibenzoxazolylphenols and related compounds with excited state proton- transfer

Kauffman,Bajwa

, p. 1613 - 1622 (2007/10/02)

A series of new 2,5-dibenzoxazolylphenols and related compounds was prepared by condensation of hydroxy- and methanesulfonamidoterephthalic acids with 2-aminophenols. These displayed excited state intramolecular proton- transfer fluorescence at room temperature and above with quantum yields as high as 0.48 and emission peaks of 492-517 nm. The methanesulfonamido group was found about as effective a proton donor as the phenolic hydroxyl group. Incorporation of substituents onto the benzoxazole moieties increased solubility of the fluors in hydrocarbon solvents in some cases, but reduced quantum yields. These fluors are of interest as wavelength shifters in a scintillating detecting medium for ionizing radiation.
