50255-90-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 50255-90-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,0,2,5 and 5 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 50255-90:
(7*5)+(6*0)+(5*2)+(4*5)+(3*5)+(2*9)+(1*0)=98
98 % 10 = 8
So 50255-90-8 is a valid CAS Registry Number.

SYNTHESIS AND PROPERTIES OF 2,2'-ANHYDRO-N-3-LUMAZINE NUCLEOSIDES
Lutz, Hermann,Pfleiderer, Wolfgang
, p. 179 - 194 (2007/10/02)
The reaction of 3-β-D-ribofuranosyllumazine, and its 6,7-dimethyl and diphenyl derivatives was studied for anhydronucleoside formation with adjacent carbonyl groups of the aglycon.Various conditions led to selective 2,2'-cyclization but no products posses
