2208-95-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 2208-95-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,2,0 and 8 respectively; the second part has 2 digits, 9 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 2208-95:
(6*2)+(5*2)+(4*0)+(3*8)+(2*9)+(1*5)=69
69 % 10 = 9
So 2208-95-9 is a valid CAS Registry Number.

Stereoselective Formation of E- or Z-Exocyclic Alkenes via Radical Cyclization Reactions oof Acetylenic Esters
Lowinger, Timothy B.,Weiler, Larry
, p. 6099 - 6101 (2007/10/02)
The intramolecular cyclization of secondary alkyl radicals with α,β-alkynyl esters proceeds stereoselectively to give either E- or Z-exocyclic alkenes, depending upon the reaction conditions.
