757240-42-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 757240-42-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 7,5,7,2,4 and 0 respectively; the second part has 2 digits, 4 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 757240-42:
(8*7)+(7*5)+(6*7)+(5*2)+(4*4)+(3*0)+(2*4)+(1*2)=169
169 % 10 = 9
So 757240-42-9 is a valid CAS Registry Number.

Liquid crystals in the series of 2,4,6-tristyryl-1,3,5-triazines
Holst, Hans Christof,Pakula, Tadeusz,Meier, Herbert
, p. 6765 - 6775 (2004)
Alkaline condensation reactions of 2,4,6-trimethyl-1,3,5-triazine (1) and substituted benzaldehydes (2a-n) yield 2,4,6-tristyryl-1,3,5-triazines (3a-n). A sufficient number and length of the alkoxy chains at the benzene rings provide liquid crystalline ph
