134863-57-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 134863-57-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,4,8,6 and 3 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 134863-57:
(8*1)+(7*3)+(6*4)+(5*8)+(4*6)+(3*3)+(2*5)+(1*7)=143
143 % 10 = 3
So 134863-57-3 is a valid CAS Registry Number.

Unprecedented observation of lactone hydrolysis by the A(Al)2 mechanism
Moore,Schwab
, p. 2331 - 2334 (2007/10/02)
Five-membered lactones are shown to undergo exchange of the ring oxygen when heated at reflux in 6 N HCl/H218O. It is concluded that lactones can be hydrolyzed by the previously unreported A(Al)2 mechanism.
