Check Digit Verification of cas no
The CAS Registry Mumber 31323-51-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,1,3,2 and 3 respectively; the second part has 2 digits, 5 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 31323-51:
(7*3)+(6*1)+(5*3)+(4*2)+(3*3)+(2*5)+(1*1)=70
70 % 10 = 0
So 31323-51-0 is a valid CAS Registry Number.

Stereoselective reduction of 2-butenolides to chiral butanolides by reductases from cultured cells of Glycine max
Shimoda, Kei,Kubota, Naoji,Hirata, Toshifumi,Kondo, Yoko,Hamada, Hiroki
, p. 1345 - 1347 (2007)
The stereoselective reduction of 2-butenolides by two reductases, p51 and p83, from cultured plant cells of Glycine max was investigated. The reduction of 2-methyl-2-butenolide by p51 reductase produced (R)-2-methylbutanolide, whereas the reduction by p83 reductase gave (S)-2-methylbutanolide. Both reductases reduced 3-methyl-2-butenolide to (R)-3-methylbutanolide. The reduction of 2,3-dimethyl-2-butenolide by p51 reductase gave (2R,3R)-2,3-dimethylbutanolide, whereas the reduction by p83 reductase produced (2S,3R)-2,3-dimethylbutanolide. The reduction of 4-alkyl-2-butenolides with these reductases was accompanied by resolution of chiral centers affording (R)-4-alkylbutanolides.

A facile synthesis of chiral ω-allyl- and ω-n-propyllactones via asymmetric allylboration of formyl esters with B- allyldiisopinocampheylborane

, p. 11 - 15 (2007/10/03)
Asymmetric allylboration of aldehydes containing an adjacent ester group with B-allyldiisopinocampheylborane, followed by hydrolysis and cyclization, provides the corresponding allyl substituted lactones in high yields and ≥92% enantiomeric excess. Hydrogenation of these lactones provides the corresponding propyl substituted lactones without any loss of optical purity.
