Check Digit Verification of cas no

The CAS Registry Mumber 6415-21-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,4,1 and 5 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 6415-21:
(6*6)+(5*4)+(4*1)+(3*5)+(2*2)+(1*1)=80
80 % 10 = 0
So 6415-21-0 is a valid CAS Registry Number.

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

Dawidowitz, Bette,Modro, Tomasz A.

, p. 128 - 134 (1984)

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

Process for preparing 0,0-diaryl N,N-dialkyl phosphoramidates

-

, (2008/06/13)

Flame retardant compounds, O,O-diaryl N,N-dialkyl phosphoramidates are prepared by reacting a phosphoramidohalidate or a phosphoramidic dihalide with a phenol in the presence of an alkali or alkaline earth metal hydroxide and a water-insoluble, water-immiscible, non-hydroxylic polar ketone which is a solvent for both the reactants and the product. High yields are obtained.
