5756-02-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 5756-02-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,7,5 and 6 respectively; the second part has 2 digits, 0 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 5756-02:
(6*5)+(5*7)+(4*5)+(3*6)+(2*0)+(1*2)=105
105 % 10 = 5
So 5756-02-5 is a valid CAS Registry Number.

Substitution of diarylphosphoryl azides with aliphatic amines catalyzed by simple rare-earth metal salts: Efficient and novel preparation of phosphoryl amides

Peng, Xin-Hua,Bai, Rui,Liu, Shanshan,Li, Zhuo,Jiao, Lin-Yu

, (2021/11/05)

A novel and high efficient protocol was disclosed herein for the rare-earth metal salt-catalyzed substitution of phosphoryl azides with amines. In this homogeneous catalysis system, different diarylphosphoryl azides and aliphatic and aromatic amines were

Phosphoric Amides. 7 - Mass Spectrometry of Phosphoric Amido Esters: Fragmentation Patterns and Migratory Aptitudes

Dawidowitz, Bette,Modro, Tomasz A.

, p. 128 - 134 (2007/10/02)

Mass spectra of 38 organophosphorus compounds, containing both phosphate ester (P(O)OR) and phosphoramidate (P(O)NR'R'') functional groups, were recorded and discussed.Attention was focused on P-N bond cleavage, which can involve simple fission, fission a
