Check Digit Verification of cas no
The CAS Registry Mumber 26911-66-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,6,9,1 and 1 respectively; the second part has 2 digits, 6 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 26911-66:
(7*2)+(6*6)+(5*9)+(4*1)+(3*1)+(2*6)+(1*6)=120
120 % 10 = 0
So 26911-66-0 is a valid CAS Registry Number.

We studied the reaction of 2-(ethoxycarbonyl)methyl-1,4,6-trimethylpyrimidinium iodide with hydrazides of N-azolyl- and C-pyrazolyl-substituted carboxylic acids, which were synthesized by reacting the respective esters with hydrazine hydrate. This reaction was shown to result in recyclization and formation of ethyl 2-(pyrazolylalkyl)- and 2-(azolylalkyl)-5,7-dimethylpyrazolo[1,5-a]pyrimidine- 3-carboxylates. Besides pyrazolopyrimidines, the separation of reaction mixture provided in some cases also another recyclization product, 2-hydroxy-5,7-dimethylpyrazolo[1,5-a]pyrimidine.
Novel route for the transformation of a pyrimidine ring using hydrazides

It has been shown from X-ray structural analytical data that the reaction of 2-ethoxycarbonylmethyl-1,4,6-trimethylpyrimidinium iodide with carboxylic acid hydrazides gives pyrazolo[1,5-a]pyrimidine derivatives and not the isomeric triazolo[4,3-a]pyridines previously reported. This novel and previously unreported rearrangement of 1,2-dialkylpyrimidinium salts occurs via recyclization of the pyrimidine ring with inclusion of a fragment of the nucleophilic reagent into the transformation product. 2006 Springer Science+Business Media, Inc.
STUDIES IN THE FIELD OF NITROGEN HETEROCYCLIC COMPOUNDS. PART XIV. SYNTHESIS OF PYRAZOLOPYRIDINE AND PYRAZOLOPYRIMIDINE DERIVATIVES

The reactions of various β-dicarbonyl compounds, β-diketones (1a-1g), β-ketoaldehydes (1h-1j) and β-ketoesters (1k-1w) with 3-amino-5-pyrazolone (2) in acetic acid solution were examined.On the basis of the experimental data obtained, a general scheme of this reaction was proposed.In the first, reversible step of the reaction, the intermediates (A, B, C) can be formed as a result of a competitive attack of three possible nucleophilic centers of 2 (C-4, N-1, -NH2) on a more positive carbonyl carbon atom of compound 1.Subsequent intermolecular cyclization of intermediates affords the corresponding pyrazolopyridines (3) and/or pyrazolopyrimidines (4, 6).It was found that the direction of cyclocondensation was noticeably affected by the nature of the dicarbonyl precursor, as well as the charge distribution and relative nucleophility of active centers of pyrazole ring within individual intermediates.
