309947-67-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 309947-67-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,0,9,9,4 and 7 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 309947-67:
(8*3)+(7*0)+(6*9)+(5*9)+(4*4)+(3*7)+(2*6)+(1*7)=179
179 % 10 = 9
So 309947-67-9 is a valid CAS Registry Number.

Synthesis of spiroaminals by bimetallic Au/Sc relay catalysis: TMS as a traceless controlling group

Zhang, Shuo,Xu, Zhengliang,Jia, Jiong,Tung, Chen-Ho,Xu, Zhenghu

supporting information, p. 12084 - 12087 (2014/12/12)

An efficient synthesis of spiroaminals over fused aminals has been successfully developed by bimetallic Au/Sc catalysis by using TMS as a traceless controlling group. This journal is

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.
