111708-59-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 111708-59-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,1,7,0 and 8 respectively; the second part has 2 digits, 5 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 111708-59:
(8*1)+(7*1)+(6*1)+(5*7)+(4*0)+(3*8)+(2*5)+(1*9)=99
99 % 10 = 9
So 111708-59-9 is a valid CAS Registry Number.

Synthesis of tricyclic azetidinones by intramolecular free radical cyclization
Just, George,Sacripante, Guerino
, p. 104 - 109 (2007/10/02)
The synthesis of strained tricyclic azetidinones was achieved by free radical cyclization of N-substituted azetidinones involving a tributyltin hydride/AIBN mediated chain reaction.The 5-exo cyclization led to benzo carbapenems 10, 12, and 13, which were
