Check Digit Verification of cas no

The CAS Registry Mumber 19090-04-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,9,0,9 and 0 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 19090-04:
(7*1)+(6*9)+(5*0)+(4*9)+(3*0)+(2*0)+(1*4)=101
101 % 10 = 1
So 19090-04-1 is a valid CAS Registry Number.

Carbonyl 1,2-transposition through triflate-mediated a-amination

Wu, Zhao,Xu, Xiaolong,Wang, Jianchun,Dong, Guangbin

, p. 734 - 740 (2021/11/16)

To date, it remains challenging to selectively migrate a carbonyl oxygen within a given molecular scaffold, especially to an adjacent carbon. In this work, we describe a simple one- or two-pot protocol that transposes a ketone to the vicinal carbon. This approach first converts the ketone to the corresponding alkenyl triflate, which can then undergo the palladium- and norbornene-catalyzed regioselective a-amination and ipso-hydrogenation enabled by a bifunctional hydrogen and nitrogen donor. The resulting "transposed enamine" intermediate can subsequently be hydrolyzed to produce the 1,2-carbonyl-migrated product. This method allows rapid access to unusual bioactive analogs through late-stage functionalization.

Rh-catalyzed intramolecular aromatic C-H insertion of α-diazo β-ketoesters: Synthesis of 4-carbonyl chroman derivatives

Zhang, Xiaolin,Lei, Mei,Zhang, Yi-Nan,Hu, Li-Hong

, p. 3400 - 3406 (2014/05/06)

A Rh-catalyzed intramolecular aromatic C-H insertion of α-diazo β-ketoesters was developed. This protocol offers a practical strategy for the synthesis of 4-carbonyl chroman derivatives with high yield and is compatible with a wide variety of substituents
