73227-27-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 73227-27-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,3,2,2 and 7 respectively; the second part has 2 digits, 2 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 73227-27:
(7*7)+(6*3)+(5*2)+(4*2)+(3*7)+(2*2)+(1*7)=117
117 % 10 = 7
So 73227-27-7 is a valid CAS Registry Number.

Characterizing triplet states of quinonoidal dinitrenes as a function of conjugation length
Minato, Masaki,Lahti, Paul M.
, p. 2187 - 2195 (1997)
Photolysis of para,para'-diazide precursors in 2-methyltetrahydrofuran gives biradical ESR spectra assignable to quinonoidal dinitrenes with excited triplet biradical states. The zero field splitting (zfs) parameters for the biradicals at 77 K are as foll
