193976-23-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 193976-23-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,3,9,7 and 6 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 193976-23:
(8*1)+(7*9)+(6*3)+(5*9)+(4*7)+(3*6)+(2*2)+(1*3)=187
187 % 10 = 7
So 193976-23-7 is a valid CAS Registry Number.

De Novo Synthesis of Phenols and Naphthols through Oxidative Cycloaromatization of Dienynes

Rong, Ming-Guang,Qin, Tian-Zhu,Liu, Xin-Rui,Wang, Hong-Fa,Zi, Weiwei

supporting information, p. 6289 - 6293 (2018/10/09)

In this work, a rhodium-catalyzed oxidative cycloaromatization of dienynes, which provides a highly straightforward and efficient way to access polysubstituted naphthols and phenols under mild conditions, is described. Challenged electron-withdrawing groups are well tolerated in this protocol, and late-stage phenyl ring formation is demonstrated.
