744-66-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 744-66-1 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 7,4 and 4 respectively; the second part has 2 digits, 6 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 744-66:
(5*7)+(4*4)+(3*4)+(2*6)+(1*6)=81
81 % 10 = 1
So 744-66-1 is a valid CAS Registry Number.

PROTON MAGNETIC RESONANCE IN NEMATIC LIQUID CRYSTALS: ACETOXYBENZAL-p-ANISIDINE, ACETOXYBENZAL-p-AMINOAZOBENZENE, AND ANISAL-p-AMINOAZOBENZENE.

Avadhanlu,Murty

, p. 221 - 230 (2007/10/12)

Proton magnetic resonance has been investigated in three nematic liquid crystals - acetoxybenzal-p-anisidine, acetoxybenzal-p-aminoazobenzene and anisal-p-aminoazobenzene, using a broad line PMR spectrometer. The results show that the five-line pattern in the first two compounds is due to the hindered rotation of the acetoxy group. The degree of order parameter S has been evaluated for the three liquid crystals from line separations and second moment measurements. These calculations also confirm the hindered rotation of the acetoxy group.
