37629-72-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 37629-72-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,7,6,2 and 9 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 37629-72:
(7*3)+(6*7)+(5*6)+(4*2)+(3*9)+(2*7)+(1*2)=144
144 % 10 = 4
So 37629-72-4 is a valid CAS Registry Number.

Peripherally fused porphyrins via the Scholl reaction: Synthesis, self-assembly, and mesomorphism

Mysliwiec, Damian,Donnio, Bertrand,Chmielewski, Piotr J.,Heinrich, Benoit,Stepien, Marcin

experimental part, p. 4822 - 4833 (2012/05/19)

Oxidative coupling of activated aryl groups attached to β-positions of the porphyrin ring provides convenient access to derivatives containing peripherally fused phenanthrene and benzo[g]chrysene units. Tetra(benzochryseno) porphyrin, reported here for the first time, contains a nonplanar, sterically locked π system and shows very intense electronic absorptions in the Q range of the electronic spectrum. Tetraphenanthroporphyrins show a tendency to aggregate in solution. In one case, a discrete dimer is formed, whose structure was investigated spectroscopically and theoretically. Derivatives bearing long alkyl chains are mesomorphic and exhibit columnar phases (tetraphenanthroporphyrins) and a monoclinic 3D phase (tetrabenzochrysenoporphyrin). The symmetry of column packing in the columnar phases is dependent on the number of alkyl chains per molecule. X-ray diffraction measurements show that, in spite of their nonplanarity, the aromatic cores in the mesophases are tightly stacked within the column. The corresponding stacking patterns were derived from the structure of the dimer, on the basis of geometrical analysis and molecular modeling.
