2138-99-0 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 2138-99-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,1,3 and 8 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 2138-99:
(6*2)+(5*1)+(4*3)+(3*8)+(2*9)+(1*9)=80
80 % 10 = 0
So 2138-99-0 is a valid CAS Registry Number.

Synthesis of Secondary Unsaturated Lactams via an Aza-Heck Reaction

Shuler, Scott A.,Yin, Guoyin,Krause, Sarah B.,Vesper, Caroline M.,Watson, Donald A.

supporting information, p. 13830 - 13833 (2016/11/06)

The preparation of unsaturated secondary lactams via the palladium-catalyzed cyclization of O-phenyl hydroxamates onto a pendent alkene is reported. This method provides rapid access to a broad range of lactams that are widely useful building blocks in alkaloid synthesis. Mechanistic studies support an aza-Heck-type pathway.

Diverse N-Heterocyclic Ring Systems via Aza-Heck Cyclizations of N-(Pentafluorobenzoyloxy)sulfonamides

Hazelden, Ian R.,Ma, Xiaofeng,Langer, Thomas,Bower, John F.

supporting information, p. 11198 - 11202 (2016/10/13)

Aza-Heck cyclizations initiated by oxidative addition of Pd0-catalysts into the N?O bond of N-(pentafluoro-benzoyloxy)sulfonamides are described. These studies, which encompass only the second class of aza-Heck reaction developed to date, provide direct access to diverse N-heterocyclic ring systems.
