1129294-89-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 1129294-89-8 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,2,9,2,9 and 4 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1129294-89:
(9*1)+(8*1)+(7*2)+(6*9)+(5*2)+(4*9)+(3*4)+(2*8)+(1*9)=168
168 % 10 = 8
So 1129294-89-8 is a valid CAS Registry Number.

Outer-Sphere Electron-Transfer Reactions of Ascorbate Anions

Williams, Nicola H.,Yandell, John K.

, p. 1133 - 1144 (2007/10/02)

Rate constants for the one-electron oxidation of ascorbate dianion (A2-) by bis(terpyridine)cobalt(III) ion (8.5*106 dm3 mol-1 s-1) and pentaammine(pyridine)ruthenium(III) ion (6.0*109 dm3 mol-1 s-1), and of the monoanion (HA-) by tetraammine(bipyridine)ruthenium(III) ion (2.1*105 dm3 mol-1 s-1) have been determined in aqueous solution at 25 deg C and ionic strength 0.1 (NaNO3 or NaClO4).It is shown that these rate constants, and other published rate constants for oxidation of HA- and A2-, are consistent with the Marcus cross relation, on the assumption that the self-exchange rate constants for both the HA-/HA. and A2-/A-. couples are 106 dm3 mol-1 s-1.One-electron redox potentials for the ascorbate/dehydroascorbate system have been derived from scattered literature data.
