174655-89-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 174655-89-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,4,6,5 and 5 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 174655-89:
(8*1)+(7*7)+(6*4)+(5*6)+(4*5)+(3*5)+(2*8)+(1*9)=171
171 % 10 = 1
So 174655-89-1 is a valid CAS Registry Number.

From tetronic acid and furfural to C(4)-halogenated, vinylated and formylated furan-2(5H)-ones and their 5-alkoxy derivatives
Lattmann,Hoffmann
, p. 155 - 163 (2007/10/03)
Tetronic acid and furfural have been elaborated into the title compounds. Palladium-catalyzed cross coupling with vinylstannanes and controlled ozonolysis followed by anhydrous workup are key reactions.
