Calculate Digit Verification of CAS Registry Number 219724-72:
(8*2)+(7*1)+(6*9)+(5*7)+(4*2)+(3*4)+(2*7)+(1*2)=148
148 % 10 = 8
So 219724-72-8 is a valid CAS Registry Number.

Unexpected reactivity of N2-benzylidene guanosine derivatives

Mons, Stephane,Lebeau, Luc,Mioskowski, Charles

, p. 9183 - 9186 (2007/10/03)

Guanosine derivatives masked at the sugar are protected at N2 by a benzylideneamine group for the first time. The free 5'-hydroxyl function reveals to be incompatible with the N2-protective group that is then rapidly hydrolyzed to regenerate the free exocyclic amine.
