858132-52-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 858132-52-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,5,8,1,3 and 2 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 858132-52:
(8*8)+(7*5)+(6*8)+(5*1)+(4*3)+(3*2)+(2*5)+(1*2)=182
182 % 10 = 2
So 858132-52-2 is a valid CAS Registry Number.

A concise synthesis of (+)-conagenin and its isomer using chiral tricyclic iminolactones

Wang, Hai-Fei,Ma, Guo-Hua,Yang, Shao-Bo,Han, Rong-Gang,Xu, Peng-Fei

, p. 1630 - 1635 (2008/12/21)

An efficient synthesis of (+)-conagenin, a novel immunomodulator produced by Streptomyces roseosporus, has been achieved via the shortest route at present. At the same time, 2-epiconagenin was synthesized according to the same methodology.

Stereoselective synthesis of an immunomodulator (+)-conagenin using dirhodium(II)-catalyzed C-H amination and chelation-controlled reductions as key steps

Yakura, Takayuki,Yoshimoto, Yuya,Ishida, Chisaki,Mabuchi, Shunsuke

, p. 930 - 932 (2007/10/03)

Stereoselective synthesis of an immunomodulator (+)-conagenin from commercially available optically active methyl 3-hydroxy-2-methylpropanoate was achieved using dirhodium(II)-catalyzed C-H amination and chelation-controlled reductions as key steps. Georg
