131033-26-6 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 131033-26-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,1,0,3 and 3 respectively; the second part has 2 digits, 2 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 131033-26:
(8*1)+(7*3)+(6*1)+(5*0)+(4*3)+(3*3)+(2*2)+(1*6)=66
66 % 10 = 6
So 131033-26-6 is a valid CAS Registry Number.

Alkanoyl ester compounds and their intermediates and method of producing the same

-

, (2008/06/13)

This invention provides a novel alkanoyl ester compound represented by general formula (I): STR1 (wherein A is of --, --O--, STR2 B is STR3 l and m are 1 or 2 provided that both are not simultaneously 2, k and n are an integer of 1 or more, respectively, provided that k>n, and R is an alkyl group), a liquid crystal composition containing this compound, a novel alkanoylphenyl compound or a novel alkanoylbiphenyl compound as an intermediate for the production of the above compound, and a method of producing the same. These novel alkanoyl ester compounds are excellent in the stability against light and the like and can take a liquid crystal state at a wide temperature range. Particularly, these compounds form liquid crystals of ferroelectricity having a large spontaneous polarization and a fast response rate by introducing an optically active group into the compound, so that they develop a very excellent effect as a starting material for optoelectronics and its related elements.
