Check Digit Verification of cas no

The CAS Registry Mumber 147895-12-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,7,8,9 and 5 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 147895-12:
(8*1)+(7*4)+(6*7)+(5*8)+(4*9)+(3*5)+(2*1)+(1*2)=173
173 % 10 = 3
So 147895-12-3 is a valid CAS Registry Number.

Preparative Bioorganic Chemistry, XVII. Reduction of a Prochiral Diketone, 9-Methyl-trans-decalin-1,8-dione, with Baker's Yeast

Mori, Kenji,Takayama, Shuichi,Yoshimura, Seiji

, p. 91 - 96 (2007/10/02)

Reduction of 9-methyl-trans-decalin-1,8-dione (1) with baker's yeast affords (8S,9R,10R)-8-hydroxy-9-methyl-trans-1-decalone (8) as the major product in 47percent yield.Its (8S,9S,10S)-isomer (9, 14percent yield) and (1S,8S)-9-methyl-trans-1,8-diol (10, 7percent yield) are obtained as minor products.Baker's yeast cannot reduce 9-methyl-cis-decalin-1,8-dione (2). Key Words: Asymmetric reduction / Baker's yeast / Yeast / Saccharomyces cerevisia / Enzymes / trans-1-Decalone derivatives / trans-1,8-Decalindione derivatives
