1. 2,3-Dihydrofuran is a dehydration product of tetrahydrofuran (THF). 2,3-Dihydrofuran is also used in the preparation of niologically active compounds such as antitumor agents.
2. 2,3-Dihydrofuran is a versatile reagent used in lanthanide-catalyzed Diels-Alder reactions with 2-pyrones and in Rh(II)-stabilized cycloadditions with vinylcarbenoids. It is applied for alkylation by active methylene compounds, catalyzed by trans-Dichlorobis(triphenyl-phosphine)-palladium(II). It is also used in the preparation of biologically active compounds such as antitumor agents.
General Description
The enantioselective Heck arylation of 2,3-dihydrofuran with aryl iodides was studied.
Check Digit Verification of cas no
The CAS Registry Mumber 1191-99-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,1,9 and 1 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1191-99:
(6*1)+(5*1)+(4*9)+(3*1)+(2*9)+(1*9)=77
77 % 10 = 7
So 1191-99-7 is a valid CAS Registry Number.
