525552-14-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 525552-14-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,2,5,5,5 and 2 respectively; the second part has 2 digits, 1 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 525552-14:
(8*5)+(7*2)+(6*5)+(5*5)+(4*5)+(3*2)+(2*1)+(1*4)=141
141 % 10 = 1
So 525552-14-1 is a valid CAS Registry Number.

Synthesis of novel macrocyclic peroxides by bis(sym-collidine)iodine (I) hexafluorophosphate-mediated cyclization of unsaturated hydroperoxides and unsaturated alcohols

Ito, Toyonari,Tokuyasu, Takahiro,Masuyama, Araki,Nojima, Masatomo,McCullough, Kevin J.

, p. 525 - 536 (2007/10/03)

Bis(sym-collidine)iodine (I) hexafluorophosphate-mediated cyclization of unsaturated hydroperoxides, prepared by a variety of different methods, afforded the corresponding 10- to 20-membered macrocyclic peroxides having two or three peroxide units located within one ring in moderate yields. By analogy, cyclization of unsaturated alcohols having one or two peroxide bond in the chain afforded the corresponding cyclic ethers. The efficiency of the latter reactions were found to be a function of the structure of the alcohols.
