24642-86-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 24642-86-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,4,6,4 and 2 respectively; the second part has 2 digits, 8 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 24642-86:
(7*2)+(6*4)+(5*6)+(4*4)+(3*2)+(2*8)+(1*6)=112
112 % 10 = 2
So 24642-86-2 is a valid CAS Registry Number.

Activation volumes for ester hydrolysis via elimination-addition

Isaacs, Neil S.,Najem, Tariq S.

, p. 1140 - 1144 (2007/10/02)

Esters that have an acidic proton α to the carbonyl group (or vinylogous situation) and a good leaving group may undergo hydrolysis by elimination to an intermediate ketene, which rapidly hydrates.Examples are found in p-hydroxybenzoate, malonate, and acetoacetate esters of nitrophenols.The evidence for this mechanism (E1 cb type) includes the independence of rate with pH in the region of dissociation of the acidic proton and, in particular, positive volumes of activation that contrast sharply with negative values typical of the more usual BAc2 mechanism of hydrolysis.
