Check Digit Verification of cas no

The CAS Registry Mumber 1421281-40-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,2,1,2,8 and 1 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1421281-40:
(9*1)+(8*4)+(7*2)+(6*1)+(5*2)+(4*8)+(3*1)+(2*4)+(1*0)=114
114 % 10 = 4
So 1421281-40-4 is a valid CAS Registry Number.

A Versatile, Traceless C-H Activation-Based Approach for the Synthesis of Heterocycles

Zhou, Shuguang,Wang, Jinhu,Zhang, Feifei,Song, Chao,Zhu, Jin

, p. 2427 - 2430 (2016)

A versatile, traceless C-H activation-based approach for the synthesis of diversified heterocycles is reported. Rh(III)-catalyzed, N-amino-directed C-H alkenylation generates either olefination products or indoles (in situ annulation) in an atom- and step-economic manner at room temperature. The remarkable reactivity endowed by this directing group enables scale-up of the reaction to a 10 g scale at a very low catalyst loading (0.01 mol %/0.1 mol %). Ex situ annulation of olefination product provides entry into an array of heterocycles.

Zirconium hydrazinediido complexes derived from cyclic hydrazines and their role in the catalytic synthesis of 1,7-annulated indoles

Scholl, Solveig A.,Wadepohl, Hubert,Gade, Lutz H.

supporting information, p. 937 - 940 (2013/03/28)

Reaction of cyclic 1,1′-disubstituted hydrazines with the bis(dimethylamido)zirconium complex [Zr{(NXyl)2N py} (NMe2)2] (1) in the presence of dmap yielded the hexacoordinate zirconium hydrazinediido
