Check Digit Verification of cas no

The CAS Registry Mumber 1380546-52-0 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,8,0,5,4 and 6 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1380546-52:
(9*1)+(8*3)+(7*8)+(6*0)+(5*5)+(4*4)+(3*6)+(2*5)+(1*2)=160
160 % 10 = 0
So 1380546-52-0 is a valid CAS Registry Number.

One-Pot Synthesis of Fused N,O-Heterocycles through Rh(III)-Catalyzed Cascade Reactions of Aromatic/Vinylic N-Alkoxy- Amides with 4-Hydroxy-2-Alkynoates

Xu, Yuanshuang,Li, Bin,Zhang, Xinying,Fan, Xuesen

supporting information, p. 2613 - 2620 (2018/04/30)

A highly efficient and regioselective synthesis of furo[3,4-c]isoquinoline-1,5(3H,4H)-diones and furo[3,4-b]pyridine-2,5(1H,7H)-diones via Rh(III)-catalyzed one-pot cascade reactions of aromatic/vinylic N-alkoxyamides with 4-hydroxy-2-alkynoates is presented. Mechanistically, the formation of the title compounds is triggered by a Rh(III)-catalyzed inert C(sp2)?H bond activation of the amide substrate followed by its [4+2] annulation and lactonization with 4-hydroxy-2-alkynoate featuring with an oxidizing and partially traceless directing group. To the best of our knowledge, this is the first example in which both the furan-2(5H)-one and the pyridin-2(1H)-one scaffolds are constructed in one pot under one set of reaction conditions. Compared with literature methods, notable features of this new protocol include facile formation of bis-heterocyclic scaffolds from readily available acyclic substrates, broad substrate scope with good tolerance of a wide range of functional groups, excellent regioselectivity and high efficiency. (Figure presented.).

Ruthenium(II)-Catalyzed C-H Functionalizations with Allenes: Versatile Allenylations and Allylations

Nakanowatari, Sachiyo,Ackermann, Lutz

supporting information, p. 16246 - 16251 (2015/11/03)

Ruthenium(II)-catalyzed direct C-H functionalization of aromatic compounds with allenes was achieved under exceedingly mild reaction conditions to yield trisubstituted allenes. The reactions of N-methoxybenzamides proceeded smoothly in an isohypsic fashio

Rh-catalyzed oxidizing group-directed ortho C-H vinylation of arenes by vinylstannanes

Prakash, Sekar,Muralirajan, Krishnamoorthy,Cheng, Chien-Hong

, p. 13362 - 13364 (2015/08/24)

An efficient method for the synthesis of functionalized vinyl arenes from the reaction of N-methoxybenzamides or N-phenoxyacetamides with vinylstannanes via rhodium(III)-catalyzed C-H activation is described. The application of the methodology for the synthesis of a natural product thalactamine and a 7-membered ring oxepine are also demonstrated.
