100103-52-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 100103-52-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,0,1,0 and 3 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 100103-52:
(8*1)+(7*0)+(6*0)+(5*1)+(4*0)+(3*3)+(2*5)+(1*2)=34
34 % 10 = 4
So 100103-52-4 is a valid CAS Registry Number.

Synthesis of Alkyl-2,3-dihydrothienofurans, Aroma Compounds of Coffee

Gorzynsky, Marek,Rewicki, Dieter

, p. 625 - 637 (2007/10/02)

Starting with 3,4-dihalofurans 1 and using furyllithium compounds as intermediates the 3-halo-4-(2-haloethyl)furans 3, 8-10, and 14 are synthesized.They are transformed into the corresponding 3-lithio-4-(2-haloethyl)furans which react with sulfur at -80 deg C to form lithium-3-thiolates and cyclize spontaneously at higher temperature to afford the 2,3-dihydrothienofurans 4, 11, and 15.By this reaction sequence 2,3-dihydro-6-methylthienofuran (kahweofuran) (4c), a roasting aroma component of coffee, is synthesized in 12percent overall yield.Eight mono-, di-, and trialkyl-substituted 2,3-dihydrothienofurans, its sulfoxide 5 as well as 4-formyl derivative 16 and the 4-methoxycarbonyl derivative 17 of kahweofuran are described.
