Check Digit Verification of cas no

The CAS Registry Mumber 205382-53-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,5,3,8 and 2 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 205382-53:
(8*2)+(7*0)+(6*5)+(5*3)+(4*8)+(3*2)+(2*5)+(1*3)=112
112 % 10 = 2
So 205382-53-2 is a valid CAS Registry Number.

Synthesis of 1,5-anhydro-D-mannitol nucleosides with a purine base moiety

Hossain, Nafizal,Herdewijn, Piet

, p. 1775 - 1779 (2007/10/03)

D-Mannitol nucleosides with a purine base moiety have been conveniently synthesized strating from 1,5-anhydro-4,6-O-benzylidene-D-glucitol. The 3-OH function of 1,5-anhydro-4,6-O-benzylidene-D-glucitol was selectively protected with t-butyldimethylsilyl group and subsequently converted to the corresponding O-triflate derivative for the introduction of the nucleobase moietes. These nucleoside derivatives were transformed to 1,5-Anhydro-6-O- MMTr-2-(N6-benzoyladenin-9-yl)-2-deoxy-3-O-TBDMS-D-mannitol and 1,5-Anhydro- 6-O-MMTr-2-(N2-isobutyrylguanin-9-yl)-2-deoxy-3-O-TBDMS-D-mannitol, useful as the building blocks for oligonucleotide synthesis. Also, the synthesis of the corresponding fully deprotected anhydrohexitol nucleosides were achieved for evaluation of antiviral activity test.
