125239-87-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 125239-87-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,5,2,3 and 9 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 125239-87:
(8*1)+(7*2)+(6*5)+(5*2)+(4*3)+(3*9)+(2*8)+(1*7)=124
124 % 10 = 4
So 125239-87-4 is a valid CAS Registry Number.

Formation of peroxynitrate from the reaction of peroxynitrite with CO2: Evidence for carbonate radical production

Goldstein, Sara,Czapski, Gidon

, p. 3458 - 3463 (1998)

The decomposition of peroxynitrite in the presence of bicarbonate and various substrates was studied using the stopped-flow technique. We have shown that peroxynitrite (ONOOH/ONOO-) reacts with excess of CO2 to form peroxynitrate (O

Cage-Escape of Geminate Radical Pairs Can Produce Peroxynitrate from Peroxynitrite under a Wide Variety of Experimental Conditions

Hodges, George R.,Ingold

, p. 10695 - 10701 (2007/10/03)

The spontaneous and CO2-catalyzed decomposition of peroxynitrite yields HO? and -CO3? radicals, respectively, together with ?NO2. The geminate HOVNO2 and -CO3?/?NO2 pairs undergo competitive in-cage collapse to nitrate and diffusive separation. Free HO? and -CO3? radicals react with H2O2 and, in the presence of O2, suitable alcohols or formate to produce superoxide, which is trapped by the ?NO2 to form peroxynitrate. The formation of peroxynitrate may influence the rate of change in optical density at 302 nm, the wavelength normally employed to monitor peroxynitrite decay, leading to misleading kinetic traces. Tetranitromethane (TNM) was used as a colorimetric probe for superoxide to quantify the yield of free HO? (27-28%) and free -CO3? (32-33%). The yields of both of these free radicals are in excellent agreement with other recent estimates. Superoxide was also detected in some oxygenated aldehyde-catalyzed peroxynitrite decompositions both by peroxynitrate formation and by its reaction with TNM. Superoxide yields, measured with TNM, were aldehyde (RCHO) dependent (R = -O2CC6H4, CH3, CH3CH2, (CH3)3C and HOCH2CHOH; yields were 15, 9, 0.8, 0, and 30%, respectively).
