Check Digit Verification of cas no

The CAS Registry Mumber 247155-31-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,4,7,1,5 and 5 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 247155-31:
(8*2)+(7*4)+(6*7)+(5*1)+(4*5)+(3*5)+(2*3)+(1*1)=133
133 % 10 = 3
So 247155-31-3 is a valid CAS Registry Number.

Synthesis and Chemoselective Reactivity of 3-aminocyclopentadienones

Rainier, Jon D.,Imbriglio, Jason E.

, p. 2037 - 2039 (1999)

(Matrix Presented) This Letter describes the synthesis and chemoselective cycloaddition chemistry of 3-aminocyclopentadienones.

The Synthesis and Chemoselective Reactivity of 3-Aminocyclopentadienones

Rainier, Jon D.,Imbriglio, Jason E.

, p. 7272 - 7276 (2007/10/03)

Iron and cobalt complexes of 3-aminocyclopentadienones have been synthesized from the [2 + 2 + 1] cycloadditions of nitrogen acetylenes and pendant alkynes. Following decomplexation, the resulting 3-aminocyclopentadienones have been subjected to chemo- and regioselective cycloadditions with dienophiles and heterodienes.

Rhodium(I)-catalyzed [2+2+2] cycloadditions with N-functionalized 1- alkynylamides: A conceptually new strategy for the regiospecific synthesis of substituted indolines

Witulski, Bernhard,Stengel, Thomas

, p. 2426 - 2430 (2007/10/03)

The regiospecific introduction of substituents into the 4-position of 2,3-dihydroindoles (indolines), which is significant for the synthesis of various natural products and pharmaceuticals, was achieved by rhodium(I)- catalyzed cyclotrimerizations of 1 wi
