(1R,2S)-1,2-<1-(18)O>-Dihydroxy-1,2-diphenylethane is a chiral organic compound characterized by its unique stereochemistry, with the R configuration at the first carbon and the S configuration at the second carbon. This molecule features two phenyl groups attached to a central carbon chain, with a hydroxyl group (-OH) at each end. The presence of the (18)O isotope in the molecule indicates that one of the oxygen atoms in the hydroxyl groups is an oxygen-18 isotope, which is heavier than the naturally occurring oxygen-16 isotope. (1R,2S)-1,2-<1-(18)O>-Dihydroxy-1,2-diphenylethane is of interest in various fields, including chemistry, pharmaceuticals, and materials science, due to its potential applications in the synthesis of chiral drugs and the study of isotope effects on chemical reactions.

Check Digit Verification of cas no

The CAS Registry Mumber 68376-03-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,8,3,7 and 6 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 68376-03:
(7*6)+(6*8)+(5*3)+(4*7)+(3*6)+(2*0)+(1*3)=154
154 % 10 = 4
So 68376-03-4 is a valid CAS Registry Number.

Asymmetric autocatalysis: Triggered by chiral isotopomer arising from oxygen isotope substitution

Kawasaki, Tsuneomi,Okano, Yasushi,Suzuki, Etsuharu,Takano, Shizuka,Oji, Shotaro,Soai, Kenso

supporting information; experimental part, p. 8131 - 8133 (2011/10/18)

Trigger happy: Chiral oxygen isotopomers of hydrobenzoin ([ 18O](R)-1 and [18O](S)-1) acted as chiral triggers to induce the enantioselective addition of iPr2Zn to pyrimidine-5-carbaldehyde. An extremely small chiral influence arising from the presence of the oxygen isotope (18O) is amplified through asymmetric autocatalysis to enantioenrich the 5-pyrimidyl alkanol product.
