109072-37-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 109072-37-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,9,0,7 and 2 respectively; the second part has 2 digits, 3 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 109072-37:
(8*1)+(7*0)+(6*9)+(5*0)+(4*7)+(3*2)+(2*3)+(1*7)=109
109 % 10 = 9
So 109072-37-9 is a valid CAS Registry Number.

The Synthesis and Properties of 3-Arylcycloheptaisoxazolylium Ions
Nitta, Makoto,Kanomata, Nobuhiro
, p. 1925 - 1928 (2007/10/02)
3-Arylcycloheptaisoxazolylium tetrafluoroborates were synthesized by the cycloaddition of tricarbonyl(2-5-η-2,4,6-cycloheptatrienone)iron with aromatic nitrile oxides followed by several reactions.The pKR+ values of these ions are less than
