25555-13-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 25555-13-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,5,5,5 and 5 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 25555-13:
(7*2)+(6*5)+(5*5)+(4*5)+(3*5)+(2*1)+(1*3)=109
109 % 10 = 9
So 25555-13-9 is a valid CAS Registry Number.

Aza-enamines, VIII. - Electrophilic Substitution reactions at the Azomethine C-Atom of Aldehyde Dialkylhydrazones: Vilsmeier Formylation and Consecutive Reactions

Brehme, Rainer

, p. 2039 - 2046 (2007/10/02)

The reaction of hydrazones 1 with the Vilsmeier reagent yields 3-phenyl-1,4,5-triaza-1,3-pentadienium salts according to their aza-enamine character.Hydrolysis of 2 gives 1-phenylglyoxal 1-dialkylhydrazones 3, which rearrange in acidic media to 1-phenylglyoxal 2-dialkylhydrazones 4.Compound 3h forms the dihydropyrroloimidazole 5 in boiling ethanol.Pyrrolotriazinium salt 6 is obtained by the reaction of 1b with the isolated Vilsmeier reagent from dimethylformamide/oxalyl chloride.

ENAMIN-ANALOGE REAKTIONEN VON ALDEHYD-N,N-DIMETHYLHYDRAZONEN.

Brehme, Rainer,Nikolajewski, Hans-Edmund

, p. 1131 - 1134 (2007/10/02)

Aldehyde-N,N-dimethylhydrazones are regarded as aza-analogous enamines.Accordingly they are substituted on the azomethynecarbon by the electrophilic sulphonylisocyanates and the Vilsmeier-reagent giving the compounds 4 and 6, respectively.
