Check Digit Verification of cas no
The CAS Registry Mumber 85211-95-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,5,2,1 and 1 respectively; the second part has 2 digits, 9 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 85211-95:
(7*8)+(6*5)+(5*2)+(4*1)+(3*1)+(2*9)+(1*5)=126
126 % 10 = 6
So 85211-95-6 is a valid CAS Registry Number.

Insertion of sulfur trioxide into allylic C-F bonds of both terminal and internal fluoro olefins is shown to form the most stable olefinic products.A mechanism involving fluoroallyl cations as intermediates is proposed.State-of-the-art ab initio calculations of the ground-state energies for two isomeric unsaturated fluoro ethers establish the slightly greater stability (5.7 kcal/mol) of a vinyl ether over the corresponding fluoro olefin.A description of the optimized geometries of these molecules is also presented.
