Check Digit Verification of cas no

The CAS Registry Mumber 2550-73-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,5,5 and 0 respectively; the second part has 2 digits, 7 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 2550-73:
(6*2)+(5*5)+(4*5)+(3*0)+(2*7)+(1*3)=74
74 % 10 = 4
So 2550-73-4 is a valid CAS Registry Number.

Synthesis and Antimicrobial Screening of Novel Azetidin-2-ones Derived from Pyromellitic Diimide via [2+2]-Cycloaddition Reaction

Ayyash

, p. 1961 - 1966 (2019)

A series of novel 2-azetidinone derivatives have been obtained starting from pyromellitic dianhydride. Pyromellitic dianhydride was converted to pyromellitic diimide using sodium cyanate, and the diimide was alkylated with ethyl chloroacetate. The resulting diester was treated with hydrazine hydrate to obtain dihydrazide which reacted with substituted pyridine-2-carbaldehydes to give the corresponding Schiff bases, and [2+2]-cycloaddition of the latter with chloroacetyl chloride in the presence of triethylamine afforded the target azetidin-2-one derivatives. The newly synthesized compounds showed high antimicrobial activities against some bacterial and fungal strains.

Synthesis of N-unsubstituted cyclic imides from anhydride with urea in deep eutectic solvent (DES) choline chloride/urea

Liu, Luxiao,Zhang, Hong-Yu,Yin, Guohui,Zhang, Yuecheng,Zhao, Jiquan

, p. 1351 - 1357 (2019/11/19)

N-Unsubstituted cyclic imides were readily synthesized in deep eutectic solvent (DES) choline chloride (ChCl)/urea from anhydrides with urea. Urea serves as both a DES component and a nitrogen source, which endows the protocol with advantages of smooth reaction, easy separation of products, simple recovery and recycling of ChCl/urea.
