"9-[2,3,5-tris-O-(phenylcarbonyl)pentofuranosyl]-3,9-dihydro-6H-purine-6-thione" is a complex organic compound with the molecular formula C31H23N5O6S. It is a derivative of purine, a heterocyclic aromatic organic compound consisting of a pyrimidine ring fused to an imidazole ring. The compound features a pentofuranosyl group, which is a five-carbon sugar with a furanose ring structure, at the 9-position of the purine. This pentofuranosyl group is substituted with three phenylcarbonyl groups at the 2, 3, and 5 positions, which are benzene rings with a carbonyl group attached. The compound also has a 3,9-dihydro-6H-purine-6-thione structure, indicating that it has a six-membered ring with a sulfur atom at the 6-position and two hydrogen atoms added to the 3 and 9 positions. 9-[2,3,5-tris-O-(phenylcarbonyl)pentofuranosyl]-3,9-dihydro-6H-purine-6-thione is likely to be of interest in the field of organic chemistry, particularly in the study of nucleoside analogs and their potential applications in medicinal chemistry.

6741-90-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 6741-90-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,7,4 and 1 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 6741-90:
(6*6)+(5*7)+(4*4)+(3*1)+(2*9)+(1*0)=108
108 % 10 = 8
So 6741-90-8 is a valid CAS Registry Number.

Synthesis and stability of GNRA-loop analogs

Woerner, Karlheinz,Strube, Thorsten,Engels, Joachim W.

, p. 2094 - 2104 (2007/10/03)

Nebularinc, 9-(β-D-ribofuranosyl)-9H-purin-2-amine, and inosine phosphoramidites 8, 16, and 17, respectively, were synthesized and incorporated into the GNRA tetraloop at different positions (see Scheme, Table, and Fig. 4). The oligomers were investigated by means of UV and CD spectroscopy to address the question of how the individual base-modified N- nuclcosides contribute to changes in H-bonding and base-stacking interactions within the loop. Several CD spectra are given and compared with each other (Figs 5 and 6). The exchange of the loop sequence in position 4 and 7 results in a distinct change in base stacking. CD-Band shifting allows us to advance the hypothesis that a transition from a GNRA-type towards a UNCG-type base stacking is observed.
