75349-93-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 75349-93-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,5,3,4 and 9 respectively; the second part has 2 digits, 9 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 75349-93:
(7*7)+(6*5)+(5*3)+(4*4)+(3*9)+(2*9)+(1*3)=158
158 % 10 = 8
So 75349-93-8 is a valid CAS Registry Number.

Synthesis of Cyclooctenynes
Petersen, Hermann,Meier, Herbert
, p. 2383 - 2397 (2007/10/02)
The three isomeric cis-cyclooctenynes 2-4 are prepared.The ring strain is enhanced in comparison to cyclooctyne (1) and increases from 1 to 4.The resulting consequences on life time and reactivity of the compounds are discussed.
