127126-27-6 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 127126-27-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,7,1,2 and 6 respectively; the second part has 2 digits, 2 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 127126-27:
(8*1)+(7*2)+(6*7)+(5*1)+(4*2)+(3*6)+(2*2)+(1*7)=106
106 % 10 = 6
So 127126-27-6 is a valid CAS Registry Number.

An efficient synthesis of enantiomerically pure (1R,2S,5S)- and (1S,2R,5R)-rosaprostol methyl esters

Murcia, M. Carmen,De La Herran, Gabriela,Plumet, Joaquín,Csaky, Aurelio G.

, p. 1553 - 1556 (2007)

We report a concise synthesis of the enantiomerically pure 1,2-trans-1,5-cis-methyl esters of rosaprostol, a prostaglandin derivative used for the treatment of gastric and duodenal ulcers, using as key step the chemo- and stereoselective Michael addition of a Grignard reagent to an unprotected hydroxycyclopentenone. Georg Thieme Verlag Stuttgart.

Total synthesis of isoprostanes via the two-component coupling process

Rodríguez, Ana R.,Spur, Bernd W.

, p. 4575 - 4579 (2007/10/03)

A short total synthesis of isoprostanes has been achieved using a two-component coupling process combined with a diastereoselective protonation under reagent control. The F1-isoprostanes were easily obtained by stereoselective reduction of the C-9 keto group.
