Check Digit Verification of cas no

The CAS Registry Mumber 128738-01-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,8,7,3 and 8 respectively; the second part has 2 digits, 0 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 128738-01:
(8*1)+(7*2)+(6*8)+(5*7)+(4*3)+(3*8)+(2*0)+(1*1)=142
142 % 10 = 2
So 128738-01-2 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.
