The CAS Registry Mumber 76609-10-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,6,6,0 and 9 respectively; the second part has 2 digits, 1 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 76609-10:
(7*7)+(6*6)+(5*6)+(4*0)+(3*9)+(2*1)+(1*0)=144
144 % 10 = 4
So 76609-10-4 is a valid CAS Registry Number.

Epoxides : Part II - Synthesis of Butyrolactones

Moussa, G. E. M.,Basyouni, M. N.,Shaban, M. E.

, p. 800 - 801 (2007/10/02)

1,1-Diarylethylene oxides (Ia-c) react with diethyl malonate in the presence of sodium ethoxide to give γ,γ-diaryl-α-ethoxycarbonyl-γ-butyrolactones (IIa-c) which yield the carboxylactones (IIIa-c) upon alkaline hydrolysis.Decarboxylation of IIIa-c furnishes the corresponding γ,γ-diaryl-γ-butyrolactones (IVa-c).
