691371-50-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 691371-50-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,9,1,3,7 and 1 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 691371-50:
(8*6)+(7*9)+(6*1)+(5*3)+(4*7)+(3*1)+(2*5)+(1*0)=173
173 % 10 = 3
So 691371-50-3 is a valid CAS Registry Number.

Synthesis of purine nucleoside analogues derived from carbocyclic 5-C-(hydroxymethyl)hexopyranoses

Hrebabecky, Hubert,Masojidkova, Milena,Holy, Antonin

, p. 435 - 452 (2007/10/03)

(1R, 2R,3R,4S)-3-(Benzyloxy)-5,5-bis(hydroxymethyl)cyclohexane-1,2,4-triol (1) was converted to (3aS,4R,5S,7aR)-4-(benzyloxy)-2-oxo-6,6-bis[(trityloxy) methyl]hexahydro-2λ,4-1,3,2-benzodioxathiol-5-ol (3) and subsequently to (3aS,4R,5S,7aR)-4-(benzyloxy)-2,2-dioxo-6,6-bis[(trityloxy) methyl]hexahydro-2λ4-1,3,2-benzodioxathiol-5-yl benzoate (4). Treatment of sulfate 4 with adenine and DBU afforded, after deprotection, 7 and 22 in low yields. Reaction of sulfite 3 with lithium azide gave (1R,2R,3S,6S)-6-azido-2-(benzyloxy)-4,4-bis[(trityloxy)methyl]-cyclohexane-1, 3-diol (10) and (1S,4R,5S,6S)-5-azido-6-(benzyloxy)-2,2-bis[(trityloxy)methyl]- cyclohexane-1,4-diol (11) which were, after separation, reduced with LAH to (1R,2R,3S,6S)-6-amino-2-(benzyloxy)-4,4-bis[(trityloxy)methyl]cyclohexane-1, 3-diol (9) and (1S,4R,5S,6S)-5-amino-6-(benzyloxy)-2,2-bis[(trityloxy)methyl] cyclohexane-1,4-diol (12). Amino derivatives 9 and 12 were transformed to (1R,2R,3S,6S)-6-(6-amino-9H-purin-9-yl)-4,4-bis(hydroxymethyl)cyclohexane-1,2, 3-triol (7), (1R,2R,3S,6S)-6-[6-(cyclopropylamino)-9H-purin-9-yl]-4,4- bis(hydroxymethyl)cyclohexane-1,2,3-triol (16), (1S,2S,3S,4R)-3-[6- (cyclopropylamino)-9H-purin-9-yl]-6,6-bis(hydroxymethyl)cyclohexane-1,2,4-triol (20), (1S,2S,3S,4R)-3-(6-amino-9H-purin-9-yl)-6,6-bis(hydroxymethyl)cyclohexane- 1,2,4-triol (22), and 2-amino-9-[(1S,2R,3R,4S)-2,3,4-trihydroxy-5,5- bis(hydroxymethyl)cyclohexyl]-9H-purin-6(1H)-one (27).
