215929-27-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 215929-27-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,5,9,2 and 9 respectively; the second part has 2 digits, 2 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 215929-27:
(8*2)+(7*1)+(6*5)+(5*9)+(4*2)+(3*9)+(2*2)+(1*7)=144
144 % 10 = 4
So 215929-27-4 is a valid CAS Registry Number.

Conjugate addition of aryl nucleophiles to α,β-unsaturated cinnamic acid derivatives containing Evans type chiral auxiliaries

Leitis, Zigmārs,Lūsis, Viesturs

, p. 843 - 851 (2016/09/02)

Cinnamides containing oxazolidin-2-one type auxiliaries have been prepared. A novel pathway to chiral 4-aryl-6-methyl-3,4-dihydrocoumrines via the asymmetric conjugate addition of arylmagnesium bromides to these cinnamides is described.

Asymmetric total synthesis of (+)-tolterodine, a new muscarinic receptor antagonist, via copper-assisted asymmetric conjugate addition of aryl Grignard reagents to 3-phenyl-prop-2-enoyl-oxazolidinones

Andersson, Pher G.,Schink, Hans E.,Oesterlund, Krister
