Check Digit Verification of cas no

The CAS Registry Mumber 91890-10-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,1,8,9 and 0 respectively; the second part has 2 digits, 1 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 91890-10:
(7*9)+(6*1)+(5*8)+(4*9)+(3*0)+(2*1)+(1*0)=147
147 % 10 = 7
So 91890-10-7 is a valid CAS Registry Number.

Achieving Aliphatic Amine Addition to Arylalkynes via the Lewis Acid Assisted Triazole-Gold (TA-Au) Catalyst System

Jia, Teng,Fan, Shengyu,Li, Fengmian,Ye, Xiaohan,Zhang, Wenke,Song, Zhiguang,Shi, Xiaodong

supporting information, p. 6019 - 6023 (2021/08/03)

Transition metal catalyzed intermolecular hydroamination of the arylalkynes with aliphatic amine is generally problematic due to the good coordination between amine and metal cation. With the combination of 1,2,3-triazole coordinated gold(I) catalyst (TA-Au) and Zn(OTf)2 cocatalyst, this challenging transformation was achieved with good to excellent yields and regioselectivity. Compared to previously reported methods, this approach offered an alternative catalyst system to achieve this fundamental chemical transformation with high efficiency and practical conditions.

N -(4-cyanotetrahydro-2 H -pyran-4-yl) and N -(1-cyanocyclohexyl) derivatives of 1,5-diarylpyrazole-3-carboxamides showing high affinity for 18 kDa translocator protein and/or cannabinoid receptors

experimental part, p. 2961 - 2970 (2011/06/24)

In order to develop improved radioligands for imaging brain CB1 receptors with positron emission tomography (PET) based on rimonabant (5-(4-chlorophenyl)-1-(2,4-dichlorophenyl)-4-methyl-N-(piperidin-1-yl) -1H-pyrazole-3-carboxamide, 1), we synt

Reactions of enamines with selectfluor: A straightforward route to difluorinated carbonyl compounds

Peng, Weimin,Shreeve, Jean'ne M.

, p. 5760 - 5763 (2007/10/03)

Reactions of enamines, preformed from β-dicarbonyl and monocarbonyl compounds, with Selectfluor (1-chloromethyl-4-fluoro-1,4-diazoniabicyclo[2.2.2] octane bis(tetrafluoroborate) under mild conditions (triethylamine (TEA) or molecular sieves) easily led to the corresponding difluorinated carbonyl compounds in high yields.
