21002-69-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 21002-69-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,1,0,0 and 2 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 21002-69:
(7*2)+(6*1)+(5*0)+(4*0)+(3*2)+(2*6)+(1*9)=47
47 % 10 = 7
So 21002-69-7 is a valid CAS Registry Number.

Tandem and Selective Conversion of Tetrahydropyranyl and Silyl Ethers to Oximes Catalyzed with Trichloroisocyanuric Acid

Aghapour, Ghasem,Abbaszadeh, Zeinab

, p. 1464 - 1470 (2015)

Direct and oxidative conversion of tetrahydropyranyl and silyl ethers to oximes is described using trichloroisocyanuric acid (TCCA) as a relatively stable and inexpensive oxidant surprisingly in a catalytic amount and hydroxylamine hydrochloride under solvent-free conditions. Oximes can be synthesized from these protected alcohols in the presence of some other functional groups with excellent chemoselectivity using the present tandem catalytic method.

supporting information; body text, p. 1413 - 1416 (2012/07/13)

The synthesis of polyfunctionalized pyrroles by reaction of a ketoxime with dimethyl acetylenedicarboxylate using europium(III) triflate as the catalyst is described. Copyright

LIQUID CHROMATOGRAPHIC RESOLUTION OF RACEMIC KETONES AS THEIR OXIME 3,5-DINITROPHENYL CARBAMATES ON A CHIRAL STATIONARY PHASE

Hyun, Myung Ho,Park, Young -Whan,Baik, In-Kyu

, p. 4735 - 4738 (2007/10/02)

Cyclic and acyclic chiral ketones have been resolved as their oxime 3,5-dinitrophenyl carbamates on a chiral stationary phase derived from (S)-1-(6,7-dimethyl-1-naphthyl)isobutylamine.

C-Nitroso compounds. Part XXXVIII. Radical reactions of α-chloro-nitroso compounds with trialkylaluminium-ether complexes

Lub, J.,Beekes, M. L.,Boer, Th. J. de

, p. 161 - 167 (2007/10/02)

Ether complexes of trialkylaluminium compounds react with α-chloro-nitroso compounds via radicals which can abstract hydrogen from various solvents.In the presence of olefinic solvents, radical addition to the double bond also takes place. When the trialk
