General Description
2'-(Dibenzylamino)-6'-(diethylamino)fluoran is a chemical compound with a molecular formula of C39H39N3O. It is a member of the fluoran family, which are compounds that contain a central fluoran ring structure. This particular compound contains two amino groups, one dibenzylamino group and one diethylamino group, which are attached to the fluoran ring. It is often used as a fluorescent dye in biological and chemical applications, as well as a pH indicator due to its ability to change color in response to changes in acidity. Additionally, it has been studied for its potential use in organic light-emitting diodes (OLEDs) due to its unique fluorescent properties.
Check Digit Verification of cas no
The CAS Registry Mumber 34372-72-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,4,3,7 and 2 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 34372-72:
(7*3)+(6*4)+(5*3)+(4*7)+(3*2)+(2*7)+(1*2)=110
110 % 10 = 0
So 34372-72-0 is a valid CAS Registry Number.

Reversibly thermochromic systems based on pH-sensitive spirolactone-derived functional dyes
Burkinshaw, Stephen M.,Griffiths, John,Towns, Andrew D.
, p. 2677 - 2683 (1998)
Composites formulated from pH-sensitive colour formers mixed with fatty acid co-solvents and acidic developers have been prepared and their thermochromic properties investigated. Possible explanations for the thermochromic effect have been considered and evidence is presented in support of a mechanism based on phase changes occurring within the compositions during heating and cooling.
