Check Digit Verification of cas no
The CAS Registry Mumber 16650-52-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,6,6,5 and 0 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 16650-52:
(7*1)+(6*6)+(5*6)+(4*5)+(3*0)+(2*5)+(1*2)=105
105 % 10 = 5
So 16650-52-5 is a valid CAS Registry Number.

The mercury-mediated decarboxylation (Pesci reaction) of naphthoic anhydrides investigated by microwave synthesis
Moseley, Jonathan D.,Gilday, John P.
, p. 4690 - 4697 (2007/10/03)
The mercury-mediated decarboxylation (Pesci reaction) of several substituted naphthoic anhydrides has been investigated by microwave synthesis. A laboratory microwave reactor was found to be ideal for small-scale preparations of this slow reaction, reducing reaction times from typically four days to less than 1 h for the three-step process. The ionic reaction medium rapidly heated to high temperatures under microwave heating and could be efficiently maintained by low microwave power settings. Generation of stoichiometric CO2 was safely contained within the reaction tubes. A simplified reaction procedure has been developed. For substituted naphthoic anhydrides, 1H NMR analysis of the naphthoate ester derivatives indicated no change in the regioisomer ratio compared to previously reported thermal values.
