Check Digit Verification of cas no
The CAS Registry Mumber 815-52-1 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 8,1 and 5 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 815-52:
(5*8)+(4*1)+(3*5)+(2*5)+(1*2)=71
71 % 10 = 1
So 815-52-1 is a valid CAS Registry Number.

A H2O2/HBr system-several directions but one choice: oxidation-bromination of secondary alcohols into mono- or dibromo ketones
Nikishin, Gennady I.,Kapustina, Nadezhda I.,Sokova, Liubov L.,Bityukov, Oleg V.,Terent'ev, Alexander O.
, p. 28632 - 28636 (2018/08/31)
In this work we found that a H2O2-HBr(aq) system allows synthesis of α-monobromo ketones and α,α′-dibromo ketones from aliphatic and secondary benzylic alcohols with yields up to 91%. It is possible to selectively direct the process toward the formation of mono- or dibromo ketones by varying the amount of hydrogen peroxide and hydrobromic acid. The convenience of application, simple equipment, multifaceted reactivity, and compliance with green chemistry principles make the application of the H2O2-HBr(aq) system very attractive in laboratories and industry. The proposed oxidation-bromination process is selective in spite of known properties of ketones to be oxidized by the Baeyer-Villiger reaction or peroxidated with the formation of compounds with the O-O moiety in the presence of hydrogen peroxide and Bronsted acids.
Oxidation of primary and secondary alkanols with the CeIII-LiBr- H2O2 system

experimental part, p. 1284 - 1288 (2011/02/23)
Action of a novel oxidation system, Ce(NO3)3? 6H2O (cat.)-LiBr (cat.)-H2O2 (stoichiometric oxidant) on primary aliphatic C6-C9 alcohols gives selectively esters, whereas secondary aliphatic C5-C9 alcohols are converted into ketones. Selectivity of these transformations is provided by slow addition of H2O2 to the other reactants.
