1-Oxaspiro[4.4]nonane-4-carboxylic acid, 2-oxo-, ethyl ester is a complex organic compound with the chemical formula C11H18O4. It is a derivative of 1-oxaspiro[4.4]nonane-4-carboxylic acid, featuring a 2-oxo group and an ethyl ester functional group. This molecule is characterized by a spiro ring system, which consists of two fused rings sharing a common atom. The 2-oxo group indicates the presence of a carbonyl group (C=O) adjacent to the spiro ring system, while the ethyl ester group is attached to the carboxylic acid moiety, forming an ester linkage. 1-Oxaspiro[4.4]nonane-4-carboxylic acid, 2-oxo-, ethyl ester is of interest in the field of organic chemistry and may have potential applications in the synthesis of pharmaceuticals or other specialty chemicals.

Check Digit Verification of cas no

The CAS Registry Mumber 61858-02-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,1,8,5 and 8 respectively; the second part has 2 digits, 0 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 61858-02:
(7*6)+(6*1)+(5*8)+(4*5)+(3*8)+(2*0)+(1*2)=134
134 % 10 = 4
So 61858-02-4 is a valid CAS Registry Number.

Cerium metal-mediated Reformatsky-type reaction with ethyl bromosuccinate for the synthesis of novel paraconic acid analogs

Rodrigues, Shirley M. M.,Nardini, Viviani,Constantino, Mauricio G.,Da Silva, Gil Valdo J.

, p. 6136 - 6137,2 (2012)

The treatment of cerium metal with ethyl bromosuccinate (1) forms the stabilized organolanthanoid intermediate (2), which reacts with carbonyl compounds in a Reformatsky-type reaction, under mild conditions, to produce functionalized γ-substituted paraconic acids (4) in good yields.
