Check Digit Verification of cas no
The CAS Registry Mumber 723335-17-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 7,2,3,3,3 and 5 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 723335-17:
(8*7)+(7*2)+(6*3)+(5*3)+(4*3)+(3*5)+(2*1)+(1*7)=139
139 % 10 = 9
So 723335-17-9 is a valid CAS Registry Number.

Acid catalysed methanolysis of 2,5-diazabicyclo[2.2.2]octane-3,6-diones: Scope and limitations

The selective methanolysis of 2,5-diazabicyclo[2.2.2]octane-3,6-dione systems is a key step in a synthetic procedure leading to 4-amino-6-oxo-2- piperidinecarboxylate systems. This reaction seems to be primarily governed by steric hindrance caused by the substituents at the 1- and 4-bridgehead positions of the dione. In absence of bulky substituents the methanolysis is directed by the secondary or tertiary nature of the two lactam moieties.
