140661-76-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 140661-76-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,0,6,6 and 1 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 140661-76:
(8*1)+(7*4)+(6*0)+(5*6)+(4*6)+(3*1)+(2*7)+(1*6)=113
113 % 10 = 3
So 140661-76-3 is a valid CAS Registry Number.

Concave Dyes with Azobenzene Units as Chromophores, Photoswitchable and Cavity-Forming Elements
Bauer, Martin,Voegtle, Fritz
, p. 1675 - 1686 (2007/10/02)
Five macrocyclic (12a-e) and three types of threefold azobenzene-bridged oligomacrocyclic compounds (15, 17, 28, 31) have been synthesized.Due to the cavity-forming chromophores at the periphery of these molecules they represent concave dyes.The watersolu
