903576-26-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 903576-26-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,0,3,5,7 and 6 respectively; the second part has 2 digits, 2 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 903576-26:
(8*9)+(7*0)+(6*3)+(5*5)+(4*7)+(3*6)+(2*2)+(1*6)=171
171 % 10 = 1
So 903576-26-1 is a valid CAS Registry Number.

pKa switching induced by the change in the π-conjugated system based on photochromism
Odo, Yuka,Matsuda, Kenji,Irie, Masahiro
, p. 4283 - 4288 (2008/02/06)
Two diarylethene derivatives 1a and 2a containing a 2, 5-diaryl-3-thienyl group have been designed and synthesized. The pKa values of these compounds change upon photoirradiation. They have a phenol group as a proton source and a pyridinium gro
