Check Digit Verification of cas no

The CAS Registry Mumber 15592-74-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,5,5,9 and 2 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 15592-74:
(7*1)+(6*5)+(5*5)+(4*9)+(3*2)+(2*7)+(1*4)=122
122 % 10 = 2
So 15592-74-2 is a valid CAS Registry Number.

Smectic liquid crystals from supramolecular guanidinium alkylbenzenesulfonates

Mathevet, Fabrice,Masson, Patrick,Nicoud, Jean-Francois,Skoulios, Antoine

, p. 2248 - 2254 (2007/10/03)

A homologous series of guanidinium alkylbenzenesulfonates from ethyl to tetradecyl were synthesized and characterised. Their thermotropic polymorphism was investigated by polarizing optical microscopy, differential scanning calorimetry, and dilatometry. The structure of the smectic liquid crystal phases obtained at high temperature with the compounds from octyl to tetradecyl was analysed by X-ray diffraction. The supramolecular assembling of the ionic species inside the smectic layers was investigated by infrared spectroscopy.
