Check Digit Verification of cas no

The CAS Registry Mumber 1346545-68-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,4,6,5,4 and 5 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1346545-68:
(9*1)+(8*3)+(7*4)+(6*6)+(5*5)+(4*4)+(3*5)+(2*6)+(1*8)=173
173 % 10 = 3
So 1346545-68-3 is a valid CAS Registry Number.

Copper-Catalyzed Synthesis of β- And δ-Carbolines by Double N-Arylation of Primary Amines

Van Phuc, Ban,Do, Ha Nam,Quan, Nguyen Minh,Tuan, Nguyen Ngoc,An, Nguyen Quang,Van Tuyen, Nguyen,Anh, Hoang Le Tuan,Hung, Tran Quang,Dang, Tuan Thanh,Langer, Peter

, p. 1004 - 1008 (2021)

Two efficient and practical approaches are reported for the synthesis of β- and δ-carbolines from 3,4-dibromopyridine. The synthesis is based on site-selective Cu-catalyzed double C-N coupling reactions and subsequent annulations by twofold Pd-catalyzed C-N coupling with amines.

First synthesis of benzopyridoiodolium salts and twofold Buchwald-Hartwig amination for the total synthesis of quindoline

Letessier, Julien,Detert, Heiner

, p. 290 - 296 (2012/04/17)

The first synthesis of cyclic benzopyridoiodolium salts is described. These hypervalent iodine intermediates are used in an efficient strategy for the construction of the -carboline core. This novel approach involves a twofold palladium-catalyzed Buchwald
