Check Digit Verification of cas no
The CAS Registry Mumber 67102-98-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,7,1,0 and 2 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 67102-98:
(7*6)+(6*7)+(5*1)+(4*0)+(3*2)+(2*9)+(1*8)=121
121 % 10 = 1
So 67102-98-1 is a valid CAS Registry Number.

Synthesis of substituted dibenz[a,c]anthracenes and an investigation of their liquid-crystalline properties

We report the synthesis of a series of 2,3,5,6-tetraalkoxydibenz[ a,c]anthracenes bearing substituents (H, OCH3, or CN) in the 11- and 12-positions and an investigation of their liquid- crystalline properties. The synthesis involved Suzuki coupling of the appropriate dibromonaphthalene and boronate ester, followed by an oxidative cyclization. Compounds 4 and 5, bearing OCH3 and H, respectively, do not exhibit any liquid-crystalline properties. In contrast, compounds 6a-c, bearing cyano groups, assemble into columnar mesophases, suggesting that electron-withdrawing groups are important for promoting columnar mesophase assembly. Analysis of the XRD revealed that compound 6b exhibits a columnar hexagonal phase, whereas compounds 6a and 6c exhibit columnar rectangular phases. The XRD data of 6a and 6b also show reflections that are consistent with antiparallel dimers within the columnar stacks, and intercolumnar spacings suggest that molecules are tilted within the columns.
