Calculate Digit Verification of CAS Registry Number 861592-66:
(8*8)+(7*6)+(6*1)+(5*5)+(4*9)+(3*2)+(2*6)+(1*6)=197
197 % 10 = 7
So 861592-66-7 is a valid CAS Registry Number.

Synthesis of substituted β-lactones by a Reformatsky reaction of carbonyl compounds, phenyl α-bromoalkanoates, and indium

Schick, Hans,Ludwig, Ralf,Kleiner, Katharina,Kunath, Annamarie

, p. 2939 - 2946 (2007/10/02)

Di-, tri-, and tetrasubstituted β-lactones are accessible in a one-step procedure by a Reformatsky reaction of phenyl α-bromoalkanoates with ketones or aldehydes at a sacrificial indium anode. With indium powder comparable results are obtained. The yield of β-lactones is significantly lower, if zinc is used instead of indium.
