Calculate Digit Verification of CAS Registry Number 17168-38:
(7*1)+(6*7)+(5*1)+(4*6)+(3*8)+(2*3)+(1*8)=116
116 % 10 = 6
So 17168-38-6 is a valid CAS Registry Number.

Iodoenolcyclization. III. A General Approach to Tetrasubstituted Furans from 2-Alkenyl-1,3-Dicarbonyl Compounds.

Antonioletti, Roberto,Cecchini, Cristina,Ciani, Barbara,Magnanti, Stefano

, p. 9019 - 9022 (1995)

2,3,4,5-tetrasubstituted furans were easily obtained from of 2-alkenyl-1,3-dicarbonyl compounds by an efficient three steps synthesis.

One-Pot Synthesis of 3-Methoxycarbonyl-2,5-dimethyl-4-substituted-phenylfurans

Niwas, Shri,Kumar, Shiv,Bhaduri, A. P.

, p. 914 - 915 (2007/10/02)

Reinvestigation of the reaction of 2-nitro-1-substituted-phenylpropanes (1-5) with methyl acetoacetate in presence of piperidine has furnished an improved one-pot synthesis of 3-methoxycarbonyl-2,5-dimethyl-4-substituted-phenylfurans (11-13).The intermediates of this reaction in a few cases have been isolated.
