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
