Check Digit Verification of cas no

The CAS Registry Mumber 173209-00-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,3,2,0 and 9 respectively; the second part has 2 digits, 0 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 173209-00:
(8*1)+(7*7)+(6*3)+(5*2)+(4*0)+(3*9)+(2*0)+(1*0)=112
112 % 10 = 2
So 173209-00-2 is a valid CAS Registry Number.

Stereochemical analysis of α1, a mating hormone of the phytopathogen Phytophthora

Ojika, Makoto,Qi, Jianhua,Kito, Yuko,Sakagami, Youji

, p. 1763 - 1765 (2007)

The stereochemistry of α1, the first identified mating hormone of the plant pathogen Phytophthora, has been unknown due to its acyclic flexible nature. Here, two stereogenic centers of α1 are determined to be (3RS,15R)-configuration by NMR analysis of the

Highly enantioselective rhodium-catalyzed hydrogenation of 2-(2-methoxy-2-oxoethyl)acrylic acid - A convenient access of enantiomerically pure isoprenoid building blocks

Ostermeier, Markus,Brunner, Bernhard,Korff, Christian,Helmchen, Guenter

, p. 3453 - 3459 (2007/10/03)

Asymmetric catalytic hydrogenation of 2-(2-methoxy-2-oxoethyl)acrylic acid (5) to give (2S)-4-methoxy-2-methyl-4-oxobutanoic acid [(S)-6] was studied. An enantiomeric excess of 99.7% ee was achieved with a catalyst formed in situ from [Rh(COD)2]BF4 and the chiral phosphite L2 in 1,2-dichloroethane as solvent. In addition, enzyme-catalyzed semi-saponification of dimethyl 2-methylsuccinate was investigated. Mono ester (S)-6 was transformed into a few compounds which can serve as C 5-building blocks in natural product syntheses. Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2003.
