309434-62-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 309434-62-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,0,9,4,3 and 4 respectively; the second part has 2 digits, 6 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 309434-62:
(8*3)+(7*0)+(6*9)+(5*4)+(4*3)+(3*4)+(2*6)+(1*2)=136
136 % 10 = 6
So 309434-62-6 is a valid CAS Registry Number.

Modulating spin delocalization in phenoxyl radicals conjugated with heterocycles
Xie, Chunping,Lahti, Paul M.,George, Clifford
, p. 3417 - 3420 (2000)
(Equation Presented) Phenoxyl radicals were synthesized having heterocyclic substituents in the 4-position. Electron spin resonance spectroscopy shows spin density can be modulated by delocalization onto the heterocycle structure, to the extent that some
