108680-98-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 108680-98-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,8,6,8 and 0 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 108680-98:
(8*1)+(7*0)+(6*8)+(5*6)+(4*8)+(3*0)+(2*9)+(1*8)=144
144 % 10 = 4
So 108680-98-4 is a valid CAS Registry Number.

SYNTHESIS OF 3-SUBSTITUTED FURANS FROM 3-C-SUBSTITUTED HEXULOSES
Fayet, Catherine,Gelas, Jacques
, p. 99 - 106 (2007/10/02)
Addition of Grignard reagents to the hexodiulose obtained from oxidation of 1,2:4,5-di-O-isopropylidene-β-D-fructopyranose gave the corresponding 3-C-substituted hexuloses.A simple procedure for the direct conversion of these C-alkylated or -arylated hexu
