331957-14-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 331957-14-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,3,1,9,5 and 7 respectively; the second part has 2 digits, 1 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 331957-14:
(8*3)+(7*3)+(6*1)+(5*9)+(4*5)+(3*7)+(2*1)+(1*4)=143
143 % 10 = 3
So 331957-14-3 is a valid CAS Registry Number.

Synthesis and photochemistry of pH-sensitive GFP chromophore analogs

Katritzky, Alan R.,Yoshioka-Tarver, Megumi,El-Gendy, Bahaa El-Dien M.,Hall, C. Dennis

, p. 2224 - 2227 (2011/05/05)

GFP chromophore analogs (7a-e, 8, and 10a,b) containing 2-thienyl-, 5-methyl-2-furyl-, 2-pyrryl, and 6-methyl-2-pyridyl-groups were synthesized and their fluorescence spectra recorded in the pH range 1-7. NMR studies showed that protonation of 8 (2-thieny
