17502-28-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 17502-28-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,7,5,0 and 2 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 17502-28:
(7*1)+(6*7)+(5*5)+(4*0)+(3*2)+(2*2)+(1*8)=92
92 % 10 = 2
So 17502-28-2 is a valid CAS Registry Number.

SYNTHESIS AND PROPERTIES OF 2-DIAZO-1,3-DICARBONYL COMPOUNDS. V. SYNTHESIS AND 1,2-NUCLEOPHILIC REARRANGEMENTS OF SOME 2-DIAZO-3-HYDROXY-1-CYCLOHEXANONES

Nikolaev, V. A.,Zhdanova, O. V.,Korobitsyna, I. K.

, p. 488 - 498 (2007/10/02)

2-Diazo-3-hydroxy, 2-diazo-3-hydroxy-5,5-dimethyl, and 2-diazo-3-hydroxy-4,4,6,6-tetramethyl-1-cyclohexanones were obtained by reduction of 2-diazo 1,3-diketones of the cyclohexane series, and their spectral characteristics were determined.Photolytic, catalytic, and thermal elimination of nitrogen in these diazo compounds is only accompanied by 1,2-nucleophilic rearrangements.During photolysis of the diazohydroxycyclohexanones in an aqueous medium the main reaction path is a Wolff rearrangement, i.e., ring contraction with the formation of hydroxy and unsaturated acids of the cyclopentane series and some of their derivatives.Acid decomposition of the diazohydroxycyclohexanones leads mainly to an alkyl shift as a result of which (hydroxymethylene)cyclopentanones are formed with ring contraction.
