14289-45-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 14289-45-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,4,2,8 and 9 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 14289-45:
(7*1)+(6*4)+(5*2)+(4*8)+(3*9)+(2*4)+(1*5)=113
113 % 10 = 3
So 14289-45-3 is a valid CAS Registry Number.

Diphenylparabanic acid as a synthon for the synthesis of α-diketones and α-ketocarboxylic acids

Watanabe, Nobuko,Hamano, Mitsutaka,Todaka, Shota,Asaeda, Takahiro,Ijuin, Hisako K.,Matsumoto, Masakatsu

, p. 632 - 639 (2012/03/22)

Diphenylparabanic acid was found to react with >2 equiv of organolithiums at -78 °C to effectively give the corresponding symmetrical α-diketones. However, upon treatment with 1 equiv of organolithium, the parabanic acid gave mainly 5-substituted 5-hydroxyimidazolidine-2,4-diones. On the other hand, Grignard reagents were less reactive toward the parabanic acid at low temperature, and selectively gave the corresponding 5- hydroxyimidazolidine-2,4-diones even if more than 1 equiv of the reagents was used. A tandem process in which the parabanic acid was first reacted with a Grignard reagent and then reacted in one-pot with an organolithium effectively gave the unsymmetrical α-diketone. 5-Substituted 5-hydroxyimidazolidine-2, 4-diones were useful as versatile precursors for preparing α- ketocarboxylic acids as well as unsymmetrical α-diketones.
