116863-90-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 116863-90-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,6,8,6 and 3 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 116863-90:
(8*1)+(7*1)+(6*6)+(5*8)+(4*6)+(3*3)+(2*9)+(1*0)=142
142 % 10 = 2
So 116863-90-2 is a valid CAS Registry Number.

A NEW CONVENIENT APPROACH TO 2,3-DISUBSTITUTED FURANS
Antonioletti, Roberto,Bonadies, Francesco,Scettri, Arrigo
, p. 73 - 74 (2007/10/02)
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.
