144448-34-0 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 144448-34-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,4,4,4 and 8 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 144448-34:
(8*1)+(7*4)+(6*4)+(5*4)+(4*4)+(3*8)+(2*3)+(1*4)=130
130 % 10 = 0
So 144448-34-0 is a valid CAS Registry Number.

Synthesis of Allosamidin

Maloisel, Jean-Luc,Vasella, Andrea,Trost, Barry M.,Vranken, David L. van

, p. 1515 - 1526 (2007/10/02)

The previously prepared disaccharide 2 was deprotected (-> 3) and transformed into the trichloroacetimidate 4.In the presence of Me3SiOTf, 4 reacted regioselectively with the racemic allosamizoline benzyl ether 5, to yield (61 percent) the pseudotrisaccharides 7-10 (44:40:9:7) and the elimination product 6 (Scheme 1).Selective dephthaloylation (MeNH2, MeOH) of 7 and 8, followed by acetylation, gave 12 (73 percent) and 13 (74 percent), respectively (Scheme 2); harsher conditions (NH2NH2*H2O, EtOH, reflux), followed by acetylation, transformed 7 into 11.Deacetylation of 11-13 yielded 14-16, respectively.Allosamidin (1) was obtained in high yield by hydrogenation of 15 under acidic conditions (Scheme 3).Similarly, 16 and 14 were transformed into 17 and 18, respectively.Preliminary data on the inhibition of endochitinases by 1 and 17 are reported.
