Preparation
The 2-ethyl-3,5-dimethylpyrazine is obtained by alkylation of dimethyl-2, 6-pyrazine; the 2,5-dimethyl-3-ethylpyrazine
is obtained by alkylation of 2,5-dimethylpyrazine with ethyllithium. A mixture of the two can be obtained by condensation of
2,3-pentanedione with propylenediamine. A mixture of the two is obtained from the side chain alkylation of trimethylpyrazine.
Check Digit Verification of cas no
The CAS Registry Mumber 27043-05-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,7,0,4 and 3 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 27043-05:
(7*2)+(6*7)+(5*0)+(4*4)+(3*3)+(2*0)+(1*5)=86
86 % 10 = 6
So 27043-05-6 is a valid CAS Registry Number.
