Check Digit Verification of cas no

The CAS Registry Mumber 1263053-66-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,6,3,0,5 and 3 respectively; the second part has 2 digits, 6 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1263053-66:
(9*1)+(8*2)+(7*6)+(6*3)+(5*0)+(4*5)+(3*3)+(2*6)+(1*6)=132
132 % 10 = 2
So 1263053-66-2 is a valid CAS Registry Number.

Palladium-catalyzed dearomative allylation of indoles with cyclopropyl acetylenes: access to indolenine derivatives

Lu, Chuan-Jun,Chen, Yu-Ting,Wang, Hong,Li, Yu-Jin

, p. 635 - 644 (2021)

A palladium-catalyzed redox-neutral allylic alkylation of indoles with cyclopropyl acetylenes has been disclosed. Various 1,3-diene indolenine framework bearing a quaternary stereocenter at the C3 position were synthesized straightforwardly in good to excellent yields with high regio- and stereoselectivities. The reaction could be further expanded to the dearomatization of naphthols to synthesize functionalized cyclohexadienones with 1,3-diene motifs. The reaction exhibited high atom economy and good functional group tolerance.
