Check Digit Verification of cas no
The CAS Registry Mumber 2787-08-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,7,8 and 7 respectively; the second part has 2 digits, 0 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 2787-08:
(6*2)+(5*7)+(4*8)+(3*7)+(2*0)+(1*8)=108
108 % 10 = 8
So 2787-08-8 is a valid CAS Registry Number.

A pyridylvinylene derivative containing piazselenole displayed high selectivity toward glutathione in the presence of other biorelevant analytes. The compound exhibited a 19?nm red-shift in absorption spectra and ～3-fold fluorescence intensity enhancement; in addition, it was possible to detect micromolar amounts of glutathione quantitatively using both red-shift absorbance and enhanced fluorescence. The mechanism of the reaction between the modified pyridylvinylene derivative and glutathione was confirmed using ESI-MS and absorption/fluorescence spectra.
