Check Digit Verification of cas no

The CAS Registry Mumber 86517-23-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,6,5,1 and 7 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 86517-23:
(7*8)+(6*6)+(5*5)+(4*1)+(3*7)+(2*2)+(1*3)=149
149 % 10 = 9
So 86517-23-9 is a valid CAS Registry Number.

Reaction des amines secondaires avec les aldehydes α,β-dibromes. Preparation d'α,β-diaminoaldehydes derives du cinnamaldehyde et nouvelle voie d'acces aux diamino-1,2 ethylenes

Klein, Jean-Louis,Combret, Jean-Claude

, p. 28 - 32 (2007/10/02)

Secondary amines react with α-bromocinnamaldehyde to yield various 2,3-bisdialkylamino-3-phenylpropanals.These diaminoaldehydes undergo two competitive rections respectively leading to α-aminocinnamaldehyde and 1,2-diamino-ethylene.Experimental conditions selectively yielding one of these compound have been studied.With 2,3-dibromobutanal the same reaction does not afford diaminoaldehyde but 1,2-diaminoethylene and a new compound, 1,2,3-triamino-1-butene.A possible reaction mechanism is discussed and a new, general one-pot synthesis of 1,2-diaminoethylene from 2-butenal with good yields is described.
