Check Digit Verification of cas no

The CAS Registry Mumber 74686-89-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,4,6,8 and 6 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 74686-89:
(7*7)+(6*4)+(5*6)+(4*8)+(3*6)+(2*8)+(1*9)=178
178 % 10 = 8
So 74686-89-8 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.
