78976-21-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 78976-21-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,8,9,7 and 6 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 78976-21:
(7*7)+(6*8)+(5*9)+(4*7)+(3*6)+(2*2)+(1*1)=193
193 % 10 = 3
So 78976-21-3 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.
