Check Digit Verification of cas no
The CAS Registry Mumber 3300-17-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,3,0 and 0 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 3300-17:
(6*3)+(5*3)+(4*0)+(3*0)+(2*1)+(1*7)=42
42 % 10 = 2
So 3300-17-2 is a valid CAS Registry Number.

The E1cb Route for Ester Hydrolysis; Volumes of Activation as an Additional Criterion of Mechanism
Isaacs, Neil S.,Najem, Tariq S.
, p. 557 - 562 (2007/10/02)
Hydrolyses of esters which possess an acidic proton at the α or vinylogous position can, in principle, hydrolyse by the E1cb route via a ketenoid intermediate.To the kinetic evidence for such a mechanism in the hydrolyses of 4-hydroxybenzoates, malonates, acetoacetates and fluorenecarboxylates is now added the further criterion of volumes of activation.Values of ΔV(excit.) for reactions proceeding by the E1cb route are positive and contrast with the negative values associated with hydrolyses by the more usual BAc2 mechanism.
