14872-32-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 14872-32-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,4,8,7 and 2 respectively; the second part has 2 digits, 3 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 14872-32:
(7*1)+(6*4)+(5*8)+(4*7)+(3*2)+(2*3)+(1*2)=113
113 % 10 = 3
So 14872-32-3 is a valid CAS Registry Number.

Synthese chiraler Azobenzole und Untersuchung der in nematischen Fluessigkristallen durch sie induzierten cholesterischen Phasen

Heppke, Gerd,Marschall, Helga,Nuernberg, Peter,Oestreicher, Feodor,Scherowsky, Guenter

, p. 2501 - 2518 (2007/10/02)

The chiral cis- and trans-azo compounds 8a - d and 9a - d with para- or ortho-standing chiral side chains as well as the trans-azoxy derivatives 17a - d and 18a - d are synthesized.The influence of the molecular structure and the distance of the chiral centre from the aromatic nucleus on screw sense and pitch of induced cholesteric phases is investigated.The cis-azo compounds 9c and d show atropisomerism.
