Check Digit Verification of cas no

The CAS Registry Mumber 1312012-32-0 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,1,2,0,1 and 2 respectively; the second part has 2 digits, 3 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1312012-32:
(9*1)+(8*3)+(7*1)+(6*2)+(5*0)+(4*1)+(3*2)+(2*3)+(1*2)=70
70 % 10 = 0
So 1312012-32-0 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

supporting information, p. 1004 - 1008 (2021/04/12)

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.

Efficient synthesis of α- and δ-carbolines by sequential Pd-catalyzed site-selective C-C and twofold C-N coupling reactions

Hung, Tran Quang,Dang, Tuan Thanh,Janke, Julia,Villinger, Alexander,Langer, Peter

supporting information, p. 1375 - 1386 (2015/01/30)

Two concise and efficient approaches were developed for the synthesis of α- and δ-carboline derivatives. The success of the synthesis relies on site-selective Suzuki-Miyaura reactions of 1-chloro-2-bromopyridine or 2,3-dibromopyridine with 2-bromophenylbo
