Check Digit Verification of cas no

The CAS Registry Mumber 84553-34-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,4,5,5 and 3 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 84553-34:
(7*8)+(6*4)+(5*5)+(4*5)+(3*3)+(2*3)+(1*4)=144
144 % 10 = 4
So 84553-34-4 is a valid CAS Registry Number.

Mecanisme d'acetolyse d'esters d'enol styreniques

Montheard, Jean-Pierre,Camps, Marcel,Chatzopoulos, Michel,Benzaid, Ahmed

, p. 109 - 116 (2007/10/02)

We have studied the reaction of enol esters in acidic media: wherein Z = H, CH3, CH2Cl, CHCl2 and CCl3.The raction is first order.Log kex = α H'0 + β (H'0 = acidity function of Hammett) with α-1.A general acid catalysis is observed.Following a discussion of possible SN, AAC2 and ASE2 mechanisms, we propose an ASE2 mechanism for this reaction.
