Check Digit Verification of cas no

The CAS Registry Mumber 1223591-64-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,2,3,5,9 and 1 respectively; the second part has 2 digits, 6 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1223591-64:
(9*1)+(8*2)+(7*2)+(6*3)+(5*5)+(4*9)+(3*1)+(2*6)+(1*4)=137
137 % 10 = 7
So 1223591-64-7 is a valid CAS Registry Number.

Liquid-crystalline polymorphism of symmetrical azobananas: Bis(4-(4-alkylphenyl)azophenyl) 2-nitroisophtalates

Zygadlo,Dardas,Nowicka,Hofmann,Galewski

, p. 283 - 291 (2011/08/02)

In this paper we present a series of novel compounds, bis(4-(4-alkylphenyl) azophenyl) 2-nitroisophtalates, which exhibit nematic and banana-type liquidcrystalline phases. The alkyl chain length varies from 1 to 18 carbons. The first ten members of this series exhibit nematic phase. The last eleven compounds exhibit banana-type liquid crystalline phases. The propyl and pentyl derivatives have extra second type of banana mesophase. Copyright Taylor & Francis Group, LLC.
