80356-76-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 80356-76-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,0,3,5 and 6 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 80356-76:
(7*8)+(6*0)+(5*3)+(4*5)+(3*6)+(2*7)+(1*6)=129
129 % 10 = 9
So 80356-76-9 is a valid CAS Registry Number.

Ueber die Synthese von 2,3-Dialkylpyrazinen
Heyns, Kurt,Behse, Ernst,Francke, Wittko
, p. 240 - 245 (2007/10/02)
2,3-Dialkylquinoxalines (4), which are available from the reaction of benzofuroxan (1) with ketones and subsequent reduction of the 2,3-dialkylquinoxaline N,N'-dioxides (3), are converted to 2,3-dialkylpyrazines (6) by oxidation-decarboxylation steps.
