17573-84-1 Usage
Synthesis
Baasner demonstrated that catalytic hydrogenolysis of 4,6-dichloro-2,5-
difluoropyrimidine gave 2,5-difluoropyrimidine.
Check Digit Verification of cas no
The CAS Registry Mumber 17573-84-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,7,5,7 and 3 respectively; the second part has 2 digits, 8 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 17573-84:
(7*1)+(6*7)+(5*5)+(4*7)+(3*3)+(2*8)+(1*4)=131
131 % 10 = 1
So 17573-84-1 is a valid CAS Registry Number.

A NEW ROUTE TO THE SYNTHESIS OF 5-FLUOROURACIL
Baasner, B.,Klauke, E.
, p. 417 - 430 (2007/10/02)
Starting from tetrafluoropyrimidine (1), selective fluorine/chlorine exchange reactions and selective hydrogenolysis of the chlorine substituents are described.Combination of these methods, together with a subsequent hydrolysis reaction, provides a new route to the synthesis of 5-fluorouracil via 4,6-dichloro-2,5-difluoropyrimidine and 4-chloro-2,5-difluoropyrimidine.
