157920-14-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 157920-14-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,7,9,2 and 0 respectively; the second part has 2 digits, 1 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 157920-14:
(8*1)+(7*5)+(6*7)+(5*9)+(4*2)+(3*0)+(2*1)+(1*4)=144
144 % 10 = 4
So 157920-14-4 is a valid CAS Registry Number.

Studies on the Role of the 2-Oxonia Cope Rearrangement in ?-Cyclizations of α-Methoxycarbonyl Oxycarbenium Ions

Lolkema, Lucie D. M.,Semeyn, Cindy,Ashek, Loulou,Hiemstra, Henk,Speckamp, W. Nico

, p. 7129 - 7140 (1994)

The 2-oxonia Cope rearrangement is shown to play an important role in Lewis acid-induced ?-cyclization reactions of a variety of methyl 2-acetoxy-2-(3-alken-1-oxy)acetates to 5- and 6-membered ring ethers.The influence of this -sigmatropic rearrangem
