The CAS Registry Mumber 91890-66-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,1,8,9 and 0 respectively; the second part has 2 digits, 6 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 91890-66:
(7*9)+(6*1)+(5*8)+(4*9)+(3*0)+(2*6)+(1*6)=163
163 % 10 = 3
So 91890-66-3 is a valid CAS Registry Number.

SYNTHESE D'α-HYDROXYALLENES α-FONCTIONNALISES A PARTIR D'α-PHENYLSELENOENALS

Lerouge, Patrice,Paulmier, Claude

, p. 1987 - 1990 (2007/10/02)

Morpholinobenzeneselenenamide (MBSe) react with enals to form α-phenylselenoenals which undergo Wittig and Horner reactions.We synthetise 1-substituted 3-phenylseleno-1,3-butadienes.Oxidation and subsequent 2,3-sigmatropic rearrangement lead to α-fonctionnalized α-hydroxyallenes.This compounds give access to 2,5 dihydrofurans.
