Check Digit Verification of cas no

The CAS Registry Mumber 1315552-22-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,1,5,5,5 and 2 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1315552-22:
(9*1)+(8*3)+(7*1)+(6*5)+(5*5)+(4*5)+(3*2)+(2*2)+(1*2)=127
127 % 10 = 7
So 1315552-22-7 is a valid CAS Registry Number.

3D and 2D supramolecular assemblies and thermotropic behaviour of a: Carbo -benzenic mesogen

Hexaalkoxy-di(phenylethynyl)-tetraphenyl-carbo-benzenes bearing six CnH2n+1 aliphatic chains (n = 12, 18) have been synthesized and characterized, including by single crystal XRD analysis. For n = 12, a liquid crystal behaviour was observed in the range of 109-130 °C. DSC, POM and PXRD analyses evidenced a rectangular columnar mesophase at 115 °C. The determined 3D lattice constants are consistent with 2D STM images of the so-called carbo-mesogen deposited on an HOPG surface.
