85249-22-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 85249-22-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,5,2,4 and 9 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 85249-22:
(7*8)+(6*5)+(5*2)+(4*4)+(3*9)+(2*2)+(1*2)=145
145 % 10 = 5
So 85249-22-5 is a valid CAS Registry Number.

The Use of Microorganisms in Organic Synthesis. II. Microbiological Asymmetric Reduction of 2-Methyl-3-oxosuccinates

Akita, Hiroyuki,Furuichi, Akiya,Koshiji, Hiroko,Horikoshi, Koki,Oishi, Takeshi

, p. 4384 - 4390 (2007/10/02)

In order to synthesize four optically active methyl 2-methylmalates (10-13), microbiological asymmetric reduction of the corresponding dimethyl 2-methyl-3-oxosuccinate (9) was carried out.The β-keto diester 9 was found to be reduced by fermenting baker's yeast (Saccharomyces cerevisiae) and Candida albicans to afford a mixture of the (2R,3R)-isomer 10 and the (2S,3R)-isomer 11.Although the optical purity of 10 produced by Candida albicans was reasonably high (95percent e.e.), optical yields of other products were unexpectedly low.However, identification of the four possible isomers 14-17 was found to be easily carried out by means of nuclear magnetic resonance spectroscopy.Keywords - α-methyl-β-keto ester; methylmalate; asymmetric reduction; microbiological reduction; yeast; methyl 2-methylmalate
