Check Digit Verification of cas no

The CAS Registry Mumber 343947-50-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,4,3,9,4 and 7 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 343947-50:
(8*3)+(7*4)+(6*3)+(5*9)+(4*4)+(3*7)+(2*5)+(1*0)=162
162 % 10 = 2
So 343947-50-2 is a valid CAS Registry Number.

Catalytic oxidation/C-H functionalization of N-arylpropiolamides by means of gold carbenoids: Concise route to 3-acyloxindoles

Qian, Deyun,Zhang, Junliang

supporting information; experimental part, p. 7082 - 7084 (2012/08/07)

An efficient catalytic C-H functionalization by means of gold carbenoids for the one-step synthesis of 3-acyloxindole derivatives has been developed. The reaction proceeds efficiently with extremely good substrate scope and significant opportunities for s

Platinum-catalyzed hydrosilylations of internal alkynes: Harnessing substituent effects to achieve high regioselectivity

Rooke, Douglas A.,Ferreira, Eric M.

supporting information; experimental part, p. 3225 - 3230 (2012/05/31)

Rule of thumb: The high yielding title reaction is described with a focus on understanding the factors that govern the regioselectivity of the process (see scheme). Electronic, steric, and functional group properties all influence the selectivity, an understanding of which allows the selective formation of trisubstituted vinylsilanes, which are synthetically useful compounds for accessing stereodefined alkenes.

Rhodium-catalyzed multicomponent-coupling reactions involving a carborhodation-cross-coupling sequence

Shintani, Ryo,Yamagami, Takafumi,Hayashi, Tamio

, p. 4799 - 4801 (2007/10/03)

(Chemical Equation Presented) A rhodium-catalyzed multicomponent-coupling reaction has been developed that involves a cross-coupling with organohalides as part of the reaction sequence. Through several experiments toward mechanistic investigations, it has
