2,5-Oxazolidinedione, 4,4-diphenyl-, commonly known as DPH, is a white crystalline solid chemical compound that is insoluble in water and has a faint odor. It is primarily recognized for its role as a cross-linking agent in polymer chemistry, particularly in the production of epoxy resins and polyurethanes. DPH also serves as a curing agent for epoxy resins and contributes to the flame-retardant properties of certain plastic materials. Due to its potential to cause skin and eye irritation, as well as respiratory irritation upon inhalation, it is crucial to handle and store DPH with appropriate safety measures.

Check Digit Verification of cas no

The CAS Registry Mumber 26314-06-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,6,3,1 and 4 respectively; the second part has 2 digits, 0 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 26314-06:
(7*2)+(6*6)+(5*3)+(4*1)+(3*4)+(2*0)+(1*6)=87
87 % 10 = 7
So 26314-06-7 is a valid CAS Registry Number.

Synthesis of sterically hindered N-acylated amino acids from N-carboxyanhydrides

Schaefer, Gabriel,Bode, Jeffrey W.

supporting information, p. 1526 - 1529 (2014/04/03)

Sterically hindered N-acyl, gem-disubstituted amino acids are easily prepared via the addition of organometallic reagents to N-carboxyanhydrides (NCA). The process tolerates a wide variety of functional groups and allows the synthesis of amide products not readily accessible by traditional acylation chemistry. The existence of an isocyanate intermediate was established by in situ IR spectroscopy.
