5032-74-6 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 5032-74-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,0,3 and 2 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 5032-74:
(6*5)+(5*0)+(4*3)+(3*2)+(2*7)+(1*4)=66
66 % 10 = 6
So 5032-74-6 is a valid CAS Registry Number.

Reaction of amides of 2,3-dibromopropionic and 2-bromoacrylic acids with pyridine and triphenylphosphine

Khachikyan,Tovmasyan,Indzhikyan

, p. 759 - 761 (2009)

By refluxing pyridine with 2,3-dibromopropionic acid amide in acetonitrile, amide of 3-bromo-2-pyridiniumbromidopropionic acid I was synthesized. The latter is inert toward the second molecule of pyridine under the used conditions. Compound I was found to

Reaction of 2,3-dihalopropionic acids and their derivatives with P- and N-nucleophiles

Khachikyan,Tovmasyan,Indzhikyan

, p. 1889 - 1894 (2008/02/03)

3-(Triphenylphosphoniochlorido)acrylic and 2,3-dichloropropionic acids react with triphenylphosphine to form 1,2-bis(triphenylphosphoniochlorido) ethane. Under analogous conditions, 2,3-dibromopropionic acid undergoes debromination followed by triphenylphosphine addition to give, after water treatment, 3-(triphenylphosphoniobromido)propionic acid. 2,3- Dihalopropionitriles react similarly, providing 3-(triphenylphosphoniohalido) propionitriles. The reaction of 2,3-dibromopropionamide with triphenylphosphine was performed to show that E-(triphenylphosphoniobromido)acrylic acid is capable, by contrast to what was reported previously, of reacting with triphenylphosphine. Pyridine forms with 2,3-dihalopropionic acids vinylpyridinium halides, while the reactions with aliphatic amines gives rise to dehydrohalogenation products.
