Check Digit Verification of cas no

The CAS Registry Mumber 336184-05-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,3,6,1,8 and 4 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 336184-05:
(8*3)+(7*3)+(6*6)+(5*1)+(4*8)+(3*4)+(2*0)+(1*5)=135
135 % 10 = 5
So 336184-05-5 is a valid CAS Registry Number.

Synthesis of areno-condensed [24]Annulenes

Meier, Herbert,Fetten, Michael,Schnorpfeil, Christoph

, p. 779 - 786 (2007/10/03)

[24]Annulenes condensed with three phenanthrene units (11a-d) or with three chrysene ring systems (22) were prepared by multi-step syntheses. The cyclic condensation reaction in the final step led to highly symmetrical compounds. Long flexible alkoxy groups attached to the periphery enhance the solubility and give rise to a strong aggregation of the molecules which was observed in solution by NMR and fluorescence excitation spectroscopy, and in the pure state by the detection of liquid crystalline phases in differential scanning calorimetry and polarization microscopy.
