87051-12-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 87051-12-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,7,0,5 and 1 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 87051-12:
(7*8)+(6*7)+(5*0)+(4*5)+(3*1)+(2*1)+(1*2)=125
125 % 10 = 5
So 87051-12-5 is a valid CAS Registry Number.

Intramolecular Oxygen Transfer on the Ozonolysis of a Diphenylcyclopentene Derivative

Jefford, Charles W.,Boukouvalas, John,Jaggi, Danielle,Kohmoto, Shigeo,Bernardinelli, Gerald

, p. 941 - 948 (1986)

The ozonolysis of cis-3,4a,7,7a-tetrahydro-3,3-dimethyl-6,7a-diphenylcyclopentatrioxine (1) in CH2Cl2 at -78 deg gave the secondary endo ozonide 2 (43percent yield) and an acetal 3 (27percent yield) derived from O-insertion at the ortho posi

Reactions of Cyclic Peroxides with Aldehydes and Ketones catalysed by Trimethylsilyl Trifluoromethanesulphonate. An Efficient Synthesis of 1,2,4-Trioxanes

Jefford, Charles W.,Boukouvalas, John,Kohmoto, Shigeo

, p. 523 - 524 (2007/10/02)

Trimethylsilyl trifluoromethanesulphonate is found to be an efficient catalyst for the reaction of 1,4-endoperoxides and 1,2-dioxetanes with aldehydes and ketones to give 1,2,4-trioxanes in high yields.
