664966-24-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 664966-24-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,6,4,9,6 and 6 respectively; the second part has 2 digits, 2 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 664966-24:
(8*6)+(7*6)+(6*4)+(5*9)+(4*6)+(3*6)+(2*2)+(1*4)=209
209 % 10 = 9
So 664966-24-9 is a valid CAS Registry Number.

Synthesis of hydroxymethyl branched [3.2.0]bicyclic nucleosides using a regioselective oxetane ring-formation.

Christensen, Nanna K,Andersen, Ann Katrine L,Schultz, Trine R,Nielsen, Poul

, p. 3738 - 3748 (2007/10/03)

Two [3.2.0]bicyclic nucleosides, 35 and 34, with one and two hydroxymethyl substituents, respectively, have been efficiently synthesized. A protected (3'-C-vinyl-beta-D-allofuranosyl)thymine derivative 28 was easily prepared from diacetone-D-glucose and the thymine moiety was protected with a BOM-group. After the introduction of a leaving group in the 2'-position, the subsequent nucleoside 31 was used as the substrate for a stereoselective dihydroxylation and a regioselective oxetane ring-formation to give after deprotection the bicyclic nucleoside 34. The surprisingly efficient formation of an oxetane was first discovered by serendipity on a corresponding methylfuranoside derivative. The allo-configured bicyclic nucleoside 34 was easily shortened to a ribo-configured analogue 35 by a diol-cleaving reaction and subsequent reduction. Both 34 and 35 are conformationally restricted in the important intermediate 04'-endo conformation.
