133442-59-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 133442-59-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,3,4,4 and 2 respectively; the second part has 2 digits, 5 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 133442-59:
(8*1)+(7*3)+(6*3)+(5*4)+(4*4)+(3*2)+(2*5)+(1*9)=108
108 % 10 = 8
So 133442-59-8 is a valid CAS Registry Number.

Synthesis of non-THF analogs of acetogenin toward simplified mimics

Fujita, Daisuke,Ichimaru, Naoya,Abe, Masato,Murai, Masatoshi,Hamada, Takeshi,Nishioka, Takaaki,Miyoshi, Hideto

, p. 5775 - 5779 (2007/10/03)

Acetogenin analogs in which the bis-adjacent THF ring was replaced with an enantioselectively synthesized 1,2-cyclopentanediol bis-ether skeleton were synthesized to obtain simplified mimics, and their inhibitory effect on mitochondrial NADH-ubiquinone oxidoreductase (complex I) was examined. The results clearly demonstrate that the 1,2-cyclopentanediol bis-ether motif can substitute for the bis-THF ring while maintaining very potent inhibitory activity at the nanomolar level.

A one-step procedure for the monoacylation of symmetrical 1,2-diols

Clarke, Paul A.,Kayaleh, Nadim E.,Smith, Martin A.,Baker, James R.,Bird, Stephan J.,Chan, Chuen

, p. 5226 - 5231 (2007/10/03)

A series of lanthanide (III) salts have been shown to catalyze the monoacylation of symmetrical 1,2-diols by carboxylic acid anhydrides with surprisingly high selectivity.

Enzymatic Preparation of Optically Pure trans-1,2-Cycloalkanediols

Seemayer, R.,Schneider, M. P.

, p. 49 - 50 (2007/10/02)

trans-1,2-Cycloalkanediols (R,R)-1,4 and (S,S)-1,3 of high optical purities are prepared by enzymatic hydrolysis and estrification catalyzed by a lipase from Pseudomonas sp. (SAM II).
