371965-72-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 371965-72-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,7,1,9,6 and 5 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 371965-72:
(8*3)+(7*7)+(6*1)+(5*9)+(4*6)+(3*5)+(2*7)+(1*2)=179
179 % 10 = 9
So 371965-72-9 is a valid CAS Registry Number.

Synthesis and structure of bicyclic enediynes via twofold carbenoid ring closure
Koenig,Pitsch,Dix,Jones
, p. 912 - 916 (2007/10/03)
Macrobicyclic enediynes were obtained in four steps from dicarboxylic diesters. The key step of the synthesis is a twofold carbenoid ring closing procedure from acyclic precursors. Crystal structure analyses showed that bicyclo[6.6.4]dienetetrayne is not
