115420-25-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 115420-25-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,5,4,2 and 0 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 115420-25:
(8*1)+(7*1)+(6*5)+(5*4)+(4*2)+(3*0)+(2*2)+(1*5)=82
82 % 10 = 2
So 115420-25-2 is a valid CAS Registry Number.

Reaction of Dilithiated Carboxylic Acids with Iodine: Evidence for the Formation of a Radical Anion Intermediate

Renaud, Philippe,Fox, Marye Anne

, p. 3745 - 3752 (2007/10/02)

The mechanism for oxidative dimerization of carboxylic acid dianions involves single electron transfer to iodine, producing an organic anion radical.Rearrangement of this species was observed with suitable substrates at a rate competitive with intermolecular reactions.The radical anion can dimerize or react with iodine.The iodide thus generated can be isolated (reaction with excess of iodine) or can participate in a polar SN2-type reaction sequence leading to dimeric products (reaction with 1/2 equiv of iodine).The interference by free amines (liberated during the metalation with lithium amides) is rationalized by the formation of a charge-transfer complex with iodine which decomposes, liberating protons.
