Check Digit Verification of cas no
The CAS Registry Mumber 143519-67-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,3,5,1 and 9 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 143519-67:
(8*1)+(7*4)+(6*3)+(5*5)+(4*1)+(3*9)+(2*6)+(1*7)=129
129 % 10 = 9
So 143519-67-9 is a valid CAS Registry Number.

A New Class of Mesomorphic Materials Designed from Calixarenes
Komori, Takashi,Shinkai, Seiji
, p. 901 - 904 (1992)
O-Methylated calixarenes (n=4, 6, and 8) coupled to C6H4-p-CmH2m+1 (m=8, 12, 14, and 16) via an azomethine linkage were synthesized.It was found that some of them show stable flow birefringence or readily form stable liquid crystals.
