Check Digit Verification of cas no

The CAS Registry Mumber 1259988-00-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,5,9,9,8 and 8 respectively; the second part has 2 digits, 0 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1259988-00:
(9*1)+(8*2)+(7*5)+(6*9)+(5*9)+(4*8)+(3*8)+(2*0)+(1*0)=215
215 % 10 = 5
So 1259988-00-5 is a valid CAS Registry Number.

Stereo- and regioselective gold-catalyzed hydroamination of internal alkynes with dialkylamines

Hesp, Kevin D.,Stradiotto, Mark

, p. 18026 - 18029 (2011/03/16)

We report the use of a P,N-ligand to support a gold complex as a state-of-the-art precatalyst for the stereoselective hydroamination of internal aryl alkynes with dialkylamines to afford E-enamine products. Substrates featuring a diverse range of functional groups on both the amine (ether, sulfide, N-Boc amine, fluoro, nitrile, nitro, alcohol, N-heterocycles, amide, ester, and carboxylic acid) and alkyne (ether, N-heterocycles, N-phthalimide amines, and silyl ethers) are accommodated with synthetically useful regioselectivity.
