Check Digit Verification of cas no

The CAS Registry Mumber 848749-78-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,4,8,7,4 and 9 respectively; the second part has 2 digits, 7 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 848749-78:
(8*8)+(7*4)+(6*8)+(5*7)+(4*4)+(3*9)+(2*7)+(1*8)=240
240 % 10 = 0
So 848749-78-0 is a valid CAS Registry Number.

Potassium tert-Butoxide-Mediated Condensation Cascade Reaction: Transition Metal-Free Synthesis of Multisubstituted Aryl Indoles and Benzofurans

Yang, Pengfei,Xu, Weiyan,Wang, Rongchao,Zhang, Min,Xie, Chunsong,Zeng, Xiaofei,Wang, Min

, p. 3658 - 3662 (2019/05/17)

An efficient and facile method to synthesize valuable disubstituted 2-aryl indoles and benzofurans in good yields has been demonstrated, based on a tert-butoxide-mediated condensation reaction involving a vinyl sulfoxide intermediate. Products are obtained from N- or O-benzyl benzaldehydes using dimethyl sulfoxide as a carbon source. The methodology features a wide functional group tolerance and transition metal-free environment. Preliminary mechanistic studies suggest that the reaction involves a tandem aldol reaction/Michael addition/dehydrosulfenylation/isomerization sequence through an ionic protocol.

Ruthenium(II)-Catalyzed Traceless C?H Functionalization Using an N?N Bond as an Internal Oxidant

Zhou, Shuguang,Wang, Jinhu,Chen, Pei,Chen, Kehao,Zhu, Jin

supporting information, p. 14508 - 14512 (2016/10/03)

A previously elusive RuII-catalyzed N?N bond-based traceless C?H functionalization strategy is reported. An N-amino (i.e., hydrazine) group is used for the directed C?H functionalization with either an alkyne or an alkene, affording an indole derivative or olefination product. The synthesis features a broad substrate scope, superior atom and step economy, as well as mild reaction conditions.
