458569-33-0 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 458569-33-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,5,8,5,6 and 9 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 458569-33:
(8*4)+(7*5)+(6*8)+(5*5)+(4*6)+(3*9)+(2*3)+(1*3)=200
200 % 10 = 0
So 458569-33-0 is a valid CAS Registry Number.

Synthesis of 3-[(2S)-azetidin-2-ylmethoxy]-5-[11C]-methylpyridine, an analogue of A-85380, via a Stille coupling

Karimi, Farhad,Lngstrm, Bengt

, p. 423 - 434 (2002)

3-[(2S)-azetidin-2-ylmethoxy]-5-[11C]-methylpyridine (5d), which might be a novel ligand for nicotinic receptors, was synthesized via coupling [11C]iodomethane with tert-butyl (2S)-2-({[5-(trimethylstannyl)pyridin-3-yl]oxy}methyl) azetidine-1-carboxylate (4) at 80°C for 5 min with tri-o-tolylphosphine-bound, unsaturated palladium(O), followed by deprotection using trifluoroacetic acid (TFA). The previous problem (solid-phase extraction before injection on semi-preparative LC) with automation of Stille coupling reactions has been overcome. In a typical experiment, 0.46 GBq of 5d was obtained from 5.2GBq of [11C]iodomethane. The decay-corrected radiochemical yield was 39% (based on the quantity [11C]iodomethane trapped). The synthesis time was 43 min from end of radionuclide production. During a production condition using 36 μAh of proton beam irradiation, a specific radioactivity of 50 GBq/ μmol of the final product was obtained in biological buffer. Copyright
