34859-37-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 34859-37-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,4,8,5 and 9 respectively; the second part has 2 digits, 3 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 34859-37:
(7*3)+(6*4)+(5*8)+(4*5)+(3*9)+(2*3)+(1*7)=145
145 % 10 = 5
So 34859-37-5 is a valid CAS Registry Number.

Syntheses and Transformations of Some 1,2,4-Oxadiazolylpyrazines
Kocevar, M.,Stanovnik, B.,Tisler, M.
, p. 1397 - 1402 (2007/10/02)
Cyanopyrazines with an ortho-amino, oxo and other groups are transformed into the corresponding amidoximes.From these the corresponding 1,2,4-oxadiazolyl derivatives can be prepared and interconversions to the corresponding pteridine 3-oxides are described.
