Check Digit Verification of cas no
The CAS Registry Mumber 38931-65-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,8,9,3 and 1 respectively; the second part has 2 digits, 6 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 38931-65:
(7*3)+(6*8)+(5*9)+(4*3)+(3*1)+(2*6)+(1*5)=146
146 % 10 = 6
So 38931-65-6 is a valid CAS Registry Number.

A New Synthesis of (+/-)-Dihydrorecifeiolide
Milenkov, Branimir,Hesse, Manfred
, p. 1323 - 1330 (1986)
Ethyl 1-(2'-formylethyl)-2-oxocyclooctane-1-carboxylate (2) prepared by Michael reaction of ethyl 2-oxocyclooctane-1-carboxylate (1) was regioselectively methylated at the aldehyde group with (CH3)2Ti2 to give 3 (Scheme 1).The alcohol 3 was treated with Bu4NF to give the deethoxycarbonylated product 4 which by distillation gave the bicyclic enol ether 5.Oxidation (m-chloroperbenzoic acid) of 5 and reduction of the resulting oxolacton 6 yielded the title compound (+/-)-dihydrorecifeiolide (7) in an overall yield of nearly 50 percent.Methylation of the aldehyde 2 with MeLi gave the ring-enlarged lacton 9 in poor yield (13 percent).The deethoxycarbonylation reaction 3 -> 4 was studied in more detail (Scheme 3).
