117461-89-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 117461-89-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,7,4,6 and 1 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 117461-89:
(8*1)+(7*1)+(6*7)+(5*4)+(4*6)+(3*1)+(2*8)+(1*9)=129
129 % 10 = 9
So 117461-89-9 is a valid CAS Registry Number.

A NEW CONVENIENT APPROACH TO 2,3-DISUBSTITUTED FURANS

α-Alkoxyalkylation of 1,3-dicarbonyl compounds with α-bromoacetaldehyde diethyl acetal, mediated by trimethylsilyl triflate, affords the corresponding adducts, which are conveniently transformed into 3-acyl- and 3-alkoxycarbonyl-furans in refluxing toluene.
