Check Digit Verification of cas no

The CAS Registry Mumber 79121-28-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,9,1,2 and 1 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 79121-28:
(7*7)+(6*9)+(5*1)+(4*2)+(3*1)+(2*2)+(1*8)=131
131 % 10 = 1
So 79121-28-1 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

supporting information, p. 2427 - 2430 (2016/06/09)

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.
