Check Digit Verification of cas no

The CAS Registry Mumber 4409-11-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,4,0 and 9 respectively; the second part has 2 digits, 1 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 4409-11:
(6*4)+(5*4)+(4*0)+(3*9)+(2*1)+(1*1)=74
74 % 10 = 4
So 4409-11-4 is a valid CAS Registry Number.

Efficient Selenium-Catalyzed Selective C(sp3)?H Oxidation of Benzylpyridines with Molecular Oxygen

Jin, Weiwei,Zheng, Poonnapa,Wong, Wing-Tak,Law, Ga-Lai

supporting information, p. 1588 - 1593 (2017/05/05)

An efficient selenium-catalyzed direct oxidation of benzylpyridines in aqueous DMSO has been successfully developed by using molecular oxygen as the oxidant. A variety of benzoylpyridines with broad functional group tolerance were obtained in modest to excellent yields and with exclusive chemoselectivity. (Figure presented.).

Base metal-catalyzed benzylic oxidation of (aryl)(heteroaryl)methanes with molecular oxygen

Sterckx, Hans,De Houwer, Johan,Mensch, Carl,Herrebout, Wouter,Tehrani, Kourosch Abbaspour,Maes, Bert U.W.

supporting information, p. 144 - 153 (2016/04/05)

The methylene group of various substituted 2- and 4-benzylpyridines, benzyldiazines and benzyl(iso)quinolines was successfully oxidized to the corresponding benzylic ketones using a copper or iron catalyst and molecular oxygen as the stoichiometric oxidant. Application of the protocol in API synthesis is exemplified by the alternative synthesis of a precursor to the antimalarial drug Mefloquine. The oxidation method can also be used to prepare metabolites of APIs which is illustrated for the natural product papaverine. ICP-MS analysis of the purified reaction products revealed that the base metal impurity was well below the regulatory limit.

Method of regulating the growth of aquatic weeds with pyridine derivatives

-

, (2008/06/13)

A method of regulating the growth of submerged and floating aquatic weeds which comprises adding a 2- or 4-substituted pyridinemethane or pyridinemethanol to a body of water containing the submerged and floating aquatic weeds to be regulated, in quantities sufficient to regulate the growth of the submerged and floating aquatic weeds therein. The disclosure also relates to novel compositions for carrying out the method.
