22280-32-6 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 22280-32-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,2,2,8 and 0 respectively; the second part has 2 digits, 3 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 22280-32:
(7*2)+(6*2)+(5*2)+(4*8)+(3*0)+(2*3)+(1*2)=76
76 % 10 = 6
So 22280-32-6 is a valid CAS Registry Number.

Rhodium/copper-catalyzed annulation of benzimides with internal alkynes: Indenone synthesis through sequential C-H and C-N cleavage

Li, Bi-Jie,Wang, Hao-Yuan,Zhu, Qi-Lei,Shi, Zhang-Jie

supporting information; experimental part, p. 3948 - 3952 (2012/05/20)

Doubled up: A rhodium(III)/copper(II) system co-catalyzes the annulation of benzimides with internal alkynes for the synthesis of indenones (see scheme; Cp=C5Me5). The reaction involves an uncommon nucleophilic addition of a transition-metal-carbon bond to an imide moiety. This novel reaction provides a facile route to synthesize indenones from readily available benzimides and internal alkynes. Copyright
