1540-21-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 1540-21-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,5,4 and 0 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1540-21:
(6*1)+(5*5)+(4*4)+(3*0)+(2*2)+(1*1)=52
52 % 10 = 2
So 1540-21-2 is a valid CAS Registry Number.

Stereospecific and Stereoselective Reactions. V. Alkylation of Active Methylene Compounds by the Use of Alcohols, Diethyl Azodicarboxylate, and Triphenylphosphine

Kurihara, Toshio,Sugizaki, Masaru,Kime, Itaru,Wada, Makoto,Mitsunobu, Oyo

, p. 2107 - 2112 (2007/10/02)

The reagent formed by the reaction of diethyl azodicarboxylate (1) and triphenylphosphine (2) reacted with alcohols and ethyl cyanoacetate (6) to give alkylated products in 30 - 80percent yields.When ethyl acetoacetate, 1,3-1,3-coclopentanedione, or 1,3-cyclohexanedione was used in place of 6, the corresponding O-alkylated products were obtained.The reaction of either (S)-(-)-ethyl lactate or (S)-(-)-ethyl 2-hydroxy-3-phenylpropionate with 1, 2, and 6, followed by hydrolysis resulted in the formation of (S)-(-)-methylsuccinic acid or (S)-(-)-benzylsuccinic acid.The results indicate that nearly complete inversion of the configuration takes place in the alkylation step.
