40090-73-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 40090-73-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,0,0,9 and 0 respectively; the second part has 2 digits, 7 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 40090-73:
(7*4)+(6*0)+(5*0)+(4*9)+(3*0)+(2*7)+(1*3)=81
81 % 10 = 1
So 40090-73-1 is a valid CAS Registry Number.

Identification of 2-chloropyrazine oxidation products and several derivatives by multinuclear magnetic resonance

Cmoch, Piotr

, p. 693 - 698 (2003)

1H, 13C, 14N and 15N NMR chemical shifts were used to prove the structures of the products of 2-chloropyrazine oxidation. It was shown that oxidation by hydrogen peroxide in acetic acid or m-chloroperbenzoic acid leads to the N4-oxide, whereas potassium persulfate in sulfuric acid gives the N1-oxide as the main product. Additionally, the results of NMR measurements of products from the nucleophilic substitution of the chlorine atom by azide anion, yielding the respective azides, and ethylation reactions of both 2-chloropyrazine N-oxides leading to the N-ethyl salts confirm the structures of both isomeric N-oxides. Protonation studies of the compounds obtained are also reported. The favoured protonation site is found to be the N atom that is not hindered by any substituents, and in some cases probably the oxygen atom of the N-oxide function. Copyright

DIAZONIUM COUPLING REACTION OF SOME DIAZINE N-OXIDES

Jovanovic, Misa V.

, p. 1115 - 1120 (2007/10/02)

Attempted deoxygenation of 2-aminopyrazine 1-oxide with HF under the diazotization conditions yielded a coupling reaction product, 2,2'-bispyrazyltriazine 1,1'-dioxide.Similarly, diazotization of 2-aminopyrimidine 1-oxide in the presence of hydrofluoric acid gave a nucleophilic hydroxylative-deoxygenation product, 5-hydroxy-2-pyrimidinediozotic acid.
