73648-80-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 73648-80-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,3,6,4 and 8 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 73648-80:
(7*7)+(6*3)+(5*6)+(4*4)+(3*8)+(2*8)+(1*0)=153
153 % 10 = 3
So 73648-80-3 is a valid CAS Registry Number.

Derivatives of (3-Anilinopropyl)methylphosphonic Acids
Kleiner, Hanss-Jerg
, p. 324 - 332 (2007/10/02)
(3-Anilinopropyl)methylphosphinic acids can be synthesized by using 2-oxo-1,2-oxaphospholanes and anilines as starting materials.Cyclisation with elimination of water gives azaphospholanes.Two simple reactions are described to prepare thioxoazaphospholanes.
