Calculate Digit Verification of CAS Registry Number 86653-09:
(7*8)+(6*6)+(5*6)+(4*5)+(3*3)+(2*0)+(1*9)=160
160 % 10 = 0
So 86653-09-0 is a valid CAS Registry Number.

, p. 829 - 832 (2007/10/02)

Enantiomerically pure (2S)-1-arenesulfonyl-2-alkanols (1) were prepared by yeast reduction of 1-arenesulfonyl-3-chloro-2-propanones, followed by epoxydation and alkylation.Reaction of dianions of 1 with aldehydes occurred at the pro(R) position of C(1) to give 1,3-diols, which were converted to (3S)-1-alken-3-ols or (2E,4S)-4-hydroxy-2-alkenenitriles in 100percent e.e.
