4127-43-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 4127-43-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,1,2 and 7 respectively; the second part has 2 digits, 4 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 4127-43:
(6*4)+(5*1)+(4*2)+(3*7)+(2*4)+(1*3)=69
69 % 10 = 9
So 4127-43-9 is a valid CAS Registry Number.

An investigative study of kinetic resolutions by the Sharpless asymmetric dihydroxylation reaction

Hamon, David P.G,Tuck, Kellie L,Christie, Hamish S

, p. 9499 - 9508 (2007/10/03)

The requirements for a highly selective kinetic resolution with the Sharpless asymmetric dihydroxylation (AD) reaction were investigated with a number of alkene substrates. It was found that with 1-phenyl-4-tert-butylcyclohexene enantioselectivity is very high, yet diastereoselectivity is poor and kinetic resolution is ineffective. With 5-methyl-2-phenylbicyclo[3.2.0]heptan-2-ene both diastereoselectivity and enantioselectivity are high and kinetic resolution is effective. It was discovered that the transition state for the product-determining step in the Sharpless AD reaction is not product-like, and effective kinetic resolution can occur when one face of a chiral alkene is hindered.
