118017-33-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 118017-33-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,8,0,1 and 7 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 118017-33:
(8*1)+(7*1)+(6*8)+(5*0)+(4*1)+(3*7)+(2*3)+(1*3)=97
97 % 10 = 7
So 118017-33-7 is a valid CAS Registry Number.

Intramolecular 4 + 3 Cycloadditions of 2-Alkoxyallylic Cations Derived from 2-Alkoxyallylic Sulfones
Harmata, Michael,Gamlath, Chandra B.
, p. 6154 - 6156 (2007/10/02)
Certain 2-alkoxyallylic sulfones lead to 2-alkoxyallylic cations, which can be intramolecularly trapped by a furan ring via a 4 + 3 cycloaddition.
