344558-99-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 344558-99-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,4,4,5,5 and 8 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 344558-99:
(8*3)+(7*4)+(6*4)+(5*5)+(4*5)+(3*8)+(2*9)+(1*9)=172
172 % 10 = 2
So 344558-99-2 is a valid CAS Registry Number.

NEW SYNTHESIS OF Γ-KETO ACIDS FROM NITROOLEFINS AND CARBOXYLIC ACID DIANIONS

Miyashita, Masaaki,Yamaguchi, Ryuji,Yoshikoshi, Akira

, p. 1505 - 1508 (1982)

As a convenient synthetic method of γ-keto acids, oxoalkylation of carboxylic acids with nitroolefins was examinated.Carboxylic acid dianions reacted with conjugated nitroolefins at low temperature (-100 deg C) and a variety of γ-keto acids were obtained on acidic workup in moderate to good yields.

Michael Reaction of Conjugated Nitro Olefins with Carboxylic Acid Dianions and with Ester Enolates: New Synthesis of γ-Keto Acids and γ-Keto Esters

Miyashita, Masaaki,Yamaguchi, Ryuji,Yoshikoshi, Akira

, p. 2857 - 2863 (2007/10/02)

Base-sensitive conjugated nitro olefins 2 reacted with lithium dianions of carboxylic acids 3 or with lithium enolates of esters 4 at a low temperature of ca. -100 deg C, and subsequent treatment of the Michael adducts with aqueous acid yielded γ-keto acids 5 or esters 5' in a one-pot operation, respectively.Results of both the reactions have been compared.Some applications of the resulting γ-keto esters in organic synthesis have also been demonstrated in lactone synthesis and cyclenone annulation.
