Check Digit Verification of cas no
The CAS Registry Mumber 6419-19-8 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 9 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 6419-19:
(6*6)+(5*4)+(4*1)+(3*9)+(2*1)+(1*9)=98
98 % 10 = 8
So 6419-19-8 is a valid CAS Registry Number.

We report here a practical and efficient synthesis of α-aminotrismethylphosphonic acid (ATMP) from (Aminomethyl)phosphonic acid (AMPA) under green conditions using microwave irradiation, via Irani-Moedritzer reaction. The ATMP was characterized by FT-IR, 1H NMR, 13C NMR, 31P-NMR and Elemental Analysis. It was found that the synthesis method gave a higher yield within very short reaction times in comparison with conventional method. In order to know the effect of phosphonomethylation moiety on the structures, electronic, vibrational and thermodynamic and optical properties for AMPA and ATMP molecules were carried out by DFT calculations in gas and water phases. Indeed, stable structures of the two molecules were optimized by using the hybrid B3LYP/6–31 G method and their HOMO-LUMO energy, MESP, global and local reactivity descriptors and NLO properties were calculated. Moreover, antioxidant activity of both investigated compounds was evaluated by DPPH. radical scavenging methods where a strong activity has been found.
