26456-28-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 26456-28-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,6,4,5 and 6 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 26456-28:
(7*2)+(6*6)+(5*4)+(4*5)+(3*6)+(2*2)+(1*8)=120
120 % 10 = 0
So 26456-28-0 is a valid CAS Registry Number.

LOW-MELTING NEMATIC 4,4 prime -BIS-(ALKYLBENZAL)-2-CHLORO-1,4-PHENYLENEDIAMINES.
Cole,Sowa
, p. 149 - 153,150, 151 (2007/10/09)
A series of 4,4 prime -bis(alkylbenzal)-2-chloro-1,4-phenylenediamines were prepared and their mesomorphic behavior characterized. All homologues showed nematic behavior with broad mesophases and rather low-melting points. The mesomorphic behavior is compared with that obtained from the 4,4 prime -bis-(alkoxybenzal)-1,4-phenylenediamine series and the 4,4 prime -bis-(alkoxybenzal)-2-chloro-1,4-phenylenediamine series.
