Check Digit Verification of cas no

The CAS Registry Mumber 75600-89-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,5,6,0 and 0 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 75600-89:
(7*7)+(6*5)+(5*6)+(4*0)+(3*0)+(2*8)+(1*9)=134
134 % 10 = 4
So 75600-89-4 is a valid CAS Registry Number.

Rearrangement of arylhydrazones of aromatic and arylaliphatic carbonyl compounds to biphenyl derivatives. 3

Fusco, R.,Sannicolo, F.

, p. 83 - 89 (2007/10/02)

The behavior toward polyphosphoric acid of arylhydrazones of aromatic carbonyl compounds (anisaldehyde, substituted benzophenones, (4-methoxyphenyl)glyoxylic acid esters) and arylaliphatic ketones (4-methoxy- and 4-aminoacetophenone) is described.Biphenyl derivatives are formed through a sigmatropic rearrangement, which often occurs in competition with the expected Fischer indole synthesis and, in the case of the 4-amino-acetophenone 2,6-dimethylphenylhydrazone, with a completely new sigmatropic rearrangement.
