Check Digit Verification of cas no
The CAS Registry Mumber 71087-74-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,1,0,8 and 7 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 71087-74:
(7*7)+(6*1)+(5*0)+(4*8)+(3*7)+(2*7)+(1*4)=126
126 % 10 = 6
So 71087-74-6 is a valid CAS Registry Number.

Regioselective Synthesis of Alkylpyrazines
Buechi, George,Galindo, Jose
, p. 2605 - 2606 (2007/10/02)
A new, regioselective synthesis of alkylpyrazines begins with condensation of α-oximido carbonyl compounds with allylamines.The resulting imines are isomerized in the presence of potassium tert-butoxide to the corresponding 1-hydroxy-1,4-diazahexatrienes.Thermal electrocyclization-aromatization to pyrazines is best performed after O-acylation of the oximes with methyl chloroformate.
