Check Digit Verification of cas no

The CAS Registry Mumber 87051-05-6 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, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 87051-05:
(7*8)+(6*7)+(5*0)+(4*5)+(3*1)+(2*0)+(1*5)=126
126 % 10 = 6
So 87051-05-6 is a valid CAS Registry Number.

NEW CHEMISTRY OF ZWITTERIONIC PEROXIDES ARISING BY PHOTOOXYGENATION OF ENOL ETHERS

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

, p. 2081 - 2088 (2007/10/02)

The rose bengal-sensitized photooxygenation of 2-methoxynorborn-2-ene (1) in acetaldehyde gave cis-1-carboxaldehyde-3-carbomethoxycyclopentane (31percent) and the cis and trans-Me derivatives of the cis-fused exo-1,2,4-trioxanes arising by addition of a molecule of oxygen and acetaldehyde to 1 at C3 and C2 respectively (13percent).Similar photooxygenation of 2-(methoxymetylidene)adamantane in the presence of acetaldehyde, propionaldehyde and pivalaldehyde gave adamantanone (31-42percent), and the cis and trans tricyclo3.7>decane-2-spiro-6'- in yields of 32-53percent.Trioxane formation under similar conditions was experienced for 1,1-di-t-butyl-2-methoxyethene and 2-(methylmercaptomethylidene)adamantane.The results are discussed in terms of an intermediate zwitterionic peroxide which can either close directly to a 1,2-dioxetane or, if aldehyde is present, condense across the CO function giving the 1,2,4-trioxane.
