13964-48-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 13964-48-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,3,9,6 and 4 respectively; the second part has 2 digits, 4 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 13964-48:
(7*1)+(6*3)+(5*9)+(4*6)+(3*4)+(2*4)+(1*8)=122
122 % 10 = 2
So 13964-48-2 is a valid CAS Registry Number.

Fluorinated Pyrimidines. Part 4. Synthesis, Properties and Stereochemical Conversion of the cis and trans Isomers of 6-Alkoxy-5-fluoro-5,6-dihydrouracils

Visser, Gerard W. M.,Wedzinga, Rinny,Klok, Robert P.,Herscheid, Jacobus D. M.

, p. 231 - 236 (2007/10/02)

The reaction of 6-acetoxy-5-fluoro-5,6-dihydrouracil with ROH (R=Me, Et, Pr, Pri, Bu, But) under acidic conditions has been investigated using 18F as a tracer.The quantitative replacement of the OAc-group proceeded predominantly with cisoid (gauche) stereochemistry, but upon prolonged heating the amount of the trans compound increased.This isomerization did not originate from epimerization at C5.The trans compounds-apart from being more stable towards substitution and elimination than the corresponding cis compounds-gave invariably substitution products with inversion of configuration, while the cis compounds mainly retained their configuration.Within the concept of the unifying ion-pair mechanism it is proposed that the trans compound reacts via an intimate protonated intermediate and the cis compound via a solvent-separated protonated intermediate.As a result, it was not the gauche attraction between the fluorine atom and the incoming nucleophile, but the poor ?-donor ability of the C-F bond that was the determining factor in the cisoid stereochemistry of 5-fluoro-5,6-dihydrouracil adducts.
