63012-76-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 63012-76-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,3,0,1 and 2 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 63012-76:
(7*6)+(6*3)+(5*0)+(4*1)+(3*2)+(2*7)+(1*6)=90
90 % 10 = 0
So 63012-76-0 is a valid CAS Registry Number.

Synthesis of new heterocondensed pteridines
Chowdhury,Shibata,Morita,Kaya,Hiratani
, p. 1173 - 1177 (2007/10/03)
Reaction of 2-aminopyrazine 1 with isothiocyanate, isocyanate or dithioketal reagent furnished pteridines 3,4 in good yield. Thioxo compound 3a was chlorinated, methylated and subsequently displaced by amines. A simple one-step synthesis of heterocondense
