139092-11-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 139092-11-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,9,0,9 and 2 respectively; the second part has 2 digits, 1 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 139092-11:
(8*1)+(7*3)+(6*9)+(5*0)+(4*9)+(3*2)+(2*1)+(1*1)=128
128 % 10 = 8
So 139092-11-8 is a valid CAS Registry Number.

An Effective System for Epoxide-Initiated Cation-Olefin Cyclization
Corey, E. J.,Sodeoka, Mikiko
, p. 7005 - 7008 (2007/10/02)
Aprotic, Lewis-acid-catalyzed cyclization of epoxy diene 1, e.g. using MeAlCl2 in CH2Cl2, affords bis-cyclization product 3 in good yield (75-79percent).
