14400-33-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 14400-33-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,4,4,0 and 0 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 14400-33:
(7*1)+(6*4)+(5*4)+(4*0)+(3*0)+(2*3)+(1*3)=60
60 % 10 = 0
So 14400-33-0 is a valid CAS Registry Number.

Reaction of N-methylazomethine ylide with aroyl azides: Synthesis of imidazolidin-4-ones
Buev, Evgeny M.,Moshkin, Vladimir S.,Sosnovskikh, Vyacheslav Y.
, p. 773 - 776 (2019)
Aryl isocyanates generated in situ from aroyl azides react with N-methylazomethine ylide generated in situ from N-methylspiroanthraceneoxazolidine at 210 °C in a microwave reactor to form 3-arylimidazolidin-4-ones in 30–81% yield.
