73920-89-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 73920-89-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,3,9,2 and 0 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 73920-89:
(7*7)+(6*3)+(5*9)+(4*2)+(3*0)+(2*8)+(1*9)=145
145 % 10 = 5
So 73920-89-5 is a valid CAS Registry Number.

Synthesis of Macrotricyclic Amines
Schmidtchen, Franz P.
, p. 864 - 874 (2007/10/02)
The synthesis of the macrotricyclic amines 14a and b with a tetrahedron skeleton is achieved by three successive cyclisations using high dilution conditions (overall yields 5.6 and 2.5percent, resp.).
