Preparation

(a) From 2-hydroxy-3-propylpyrazine by ethylation with diazomethane; the 2-hydroxy-3-propylpyrazine is pre pared by condensing norvaline amide hydrochloride with glyxoal (a + b + c). A mixture can be obtained by methoxylation of isopropylchloropyrazine.

Check Digit Verification of cas no

The CAS Registry Mumber 93905-03-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,3,9,0 and 5 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 93905-03:
(7*9)+(6*3)+(5*9)+(4*0)+(3*5)+(2*0)+(1*3)=144
144 % 10 = 4
So 93905-03-4 is a valid CAS Registry Number.
