185138-92-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 185138-92-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,5,1,3 and 8 respectively; the second part has 2 digits, 9 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 185138-92:
(8*1)+(7*8)+(6*5)+(5*1)+(4*3)+(3*8)+(2*9)+(1*2)=155
155 % 10 = 5
So 185138-92-5 is a valid CAS Registry Number.

Taurospongins B and C, new acetylenic fatty acid derivatives possessing a taurine amide residue from a marine sponge of the family Spongiidae

Kubota, Takaaki,Suzuki, Haruna,Takahashi-Nakaguchi, Azusa,Fromont, Jane,Gonoi, Tohru,Kobayashi, Jun'Ichi

, p. 11073 - 11079 (2014)

Two new acetylenic fatty acid derivatives possessing a taurine amide residue, taurospongins B (1) and C (2), have been isolated from an Okinawan marine sponge of the family Spongiidae. The gross structures of 1 and 2 were elucidated on the basis of their spectral data, especially 2D NMR and FABMS/MS data. The absolute configurations for 1 and 2 were established by chemical means. Taurospongin C (2) showed inhibitory activity against Cryptococcus neoformans.

Synthesis of taurospongin A

Wu, Boshen,Mallinger, Aurelie,Robertson, Jeremy

supporting information; experimental part, p. 2818 - 2821 (2010/09/03)

(Figure presented) Two new routes to the C(1-10) carboxylic acid core of taurospongin A are presented. In the first route, overall asymmetric hydration of a C(2)-C(3) alkene is achieved by Sharpless AD and selective deoxygenation at C(2); in the second route, the C(3) stereogenic center is set by Tietze asymmetric allylation. A short synthesis of the C(1′-25′) fatty acid combines with the product from the first route to complete the total synthesis of taurospongin A.

Use of π-allyltricarbonyliron lactone complexes in the synthesis of taurospongin A: A potent inhibitor of DNA polymerase β and HIV reverse transcriptase

Hollowood, Christopher J.,Yamanoi, Shigeo,Ley, Steven V.

, p. 1664 - 1675 (2007/10/03)

The total synthesis of taurospongin A by two new approaches has been achieved where π-allyltricarbonyliron lactone complexes have been used to control highly stereoselective additions of the nucleophiles to a carbonyl unit located in the side chain of the

Synthesis of taurospongin A: a potent inhibitor of DNA polymerase and HIV reverse transcriptase, using pi-allyltricarbonyliron lactone complexes.

Hollowood, Christopher J,Ley, Steven V,Yamanoi, Shigeo

, p. 1624 - 1625 (2007/10/03)

The synthesis of taurospongin A has been achieved using, as a key step, a pi-allyltricarbonyliron lactone complex to control a highly stereoselective addition of a methyl group to a carbonyl unit located in the side chain of the complex.
