Check Digit Verification of cas no

The CAS Registry Mumber 130709-90-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,0,7,0 and 9 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 130709-90:
(8*1)+(7*3)+(6*0)+(5*7)+(4*0)+(3*9)+(2*9)+(1*0)=109
109 % 10 = 9
So 130709-90-9 is a valid CAS Registry Number.

Electroclinic Effect in Unsymmetrycal Dimeric Liquid Crystals Composed of Two Non-Identical Chiral Mesogenic Entities

Yelamaggad, C. V.,Nagamani, S. Anitha,Rao, D. S. Shankar,Prasad, S. Krishna,Hiremath, U. S.

, p. 1 - 18 (2007/10/03)

We report the synthesis and physical characterization of two unsymmetrical dimeric liquid crystals containing two different chiral mesogenic segments, namely, a tolan unit with (S)-2-octyloxy tail and a cholesteryl ester unit which are separated by a n-bu

Highly twisting enantiomeric radial multiyne dopants for discotic liquid-crystalline systems

Booth, Christopher J.,Krueerke, Daniel,Heppke, Gerd

, p. 927 - 934 (2007/10/03)

The synthesis and dopant properties of both the (R,R,R,R,R)- and (S,S,S,S,S)-hexadecyloxy{pentakis[4-(1-methylheptyloxy)-phenylethynyl]}benzene enantiomers are described. Although the materials were found not to be liquid-crystalline, it was found possibl
