1153-34-0 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 1153-34-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,1,5 and 3 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1153-34:
(6*1)+(5*1)+(4*5)+(3*3)+(2*3)+(1*4)=50
50 % 10 = 0
So 1153-34-0 is a valid CAS Registry Number.

A short efficient synthesis of ambraketal (four steps) and epiambraketal (five steps) from sclareol

Martres, Paul,Perfetti, Patricia,Zahra, Jean-Pierre,Waegell, Bernard

, p. 97 - 98 (2007/10/02)

Ambraketal 7 and epiambraketal 8 are synthesized efficiently from sclareol 1. The key intermediate 5 is obtained by a regioselective elimination of ketoacetate 4 resulting from the side chain oxidative degradation of 1 by ruthenium tetroxide generated in situ.

Novel Diastereoselective Routes for the Synthesis of the Ambergris ketals

Costa, Maria do Ceu,Tavares, Regina,Motherwell, William B.,Curto, Maria Joao Marcelo

, p. 8839 - 8842 (2007/10/02)

New processes have been developed which allow the stereoselective syntheses of the ambergris ketals 8α,13;13,17-diepoxi-14,15-dinorlabdane 1 and 8β,13;13,17-diepoxi-14,15-dinorlabdane 2, through selection of the appropriate catalyst for the δ,ε-epoxycarbonyl rearrangement of the key intermediate 3, which is, in turn, obtained by controlled oxidation of anticopalic acid 6.

SYNTHESIS OF AMBRACETAL AND EPI-8-AMBRACETAL

Martres, Paul,Perfetti, Patricia,Zahra, Jean-Pierre,Waegell, Bernard

, p. 765 - 766 (2007/10/02)

A protection-deprotection sequence is used in order to control the formation of the exocyclic double bond of compound 10 which is further used for the synthesis of the title compounds.
