1089730-91-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 1089730-91-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,8,9,7,3 and 0 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1089730-91:
(9*1)+(8*0)+(7*8)+(6*9)+(5*7)+(4*3)+(3*0)+(2*9)+(1*1)=185
185 % 10 = 5
So 1089730-91-5 is a valid CAS Registry Number.

Three-component synthesis of cryofluorescent 2,4-disubstituted 3H-1,5-benzodiazepines - Conformational control of emission properties

Willy, Benjamin,Dallos, Timea,Rominger, Frank,Sch?nhaber, Jan,Müller, Thomas J. J.

, p. 4796 - 4805 (2008)

2,4-Disubstituted benzodiazepines are readily synthesized in good yields from acyl chlorides, terminal alkynes, and benzene-1,2-diamines by a consecutive one-pot, three-component Sonogashira coupling/Michael addition/ cyclocondensation sequence. These diazepines display intense solid-state fluorescence, but only weak emission in solution at room temperature. The absorption and emission maxima can be controlled by the substitution pattern. Upon cooling, however, the phenomenon of cryofluorescence can be observed. X-ray structure analysis and temperature-dependent NMR indicate that freezing out of conformational interconversions is the source of the thermochromicity observed upon UV excitation.
