Calculate Digit Verification of CAS Registry Number 128737-99:
(8*1)+(7*2)+(6*8)+(5*7)+(4*3)+(3*7)+(2*9)+(1*9)=165
165 % 10 = 5
So 128737-99-5 is a valid CAS Registry Number.

Molecular complexes of hydrazones - VIII. Nitrofluorenes and arylhydrazones

Bruni, Paolo,Cardillo, Barbara,Giorgini, Elisabetta,Tosi, Giorgio,Bocelli, Gabriele,Cantoni, Andrea

, p. 389 - 396 (2007/10/02)

Nitrofluorenes form ?-? complexes with a series of hydrazones both in solution and in the solid state.The properties of the complexes, discussed on the basis of u.v.-vis and FT-i.r. data, suggest the presence of weak interactions, as confirmed by the formation constants and X-ray analysis.The presence of some degree of charge transfer is confirmed by ESR determinations.The X-ray analysis of the complex of benzaldehydediphenylhydrazone with 2,4,7-trinitrofluorenone is also reported.
