Check Digit Verification of cas no

The CAS Registry Mumber 1380502-88-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,8,0,5,0 and 2 respectively; the second part has 2 digits, 8 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1380502-88:
(9*1)+(8*3)+(7*8)+(6*0)+(5*5)+(4*0)+(3*2)+(2*8)+(1*8)=144
144 % 10 = 4
So 1380502-88-4 is a valid CAS Registry Number.

Rh(i)-catalyzed decarbonylative direct C2-olefination of indoles with vinyl carboxylic acids

Zhang, Lingjuan,Qiu, Ruiying,Xue, Xiao,Pan, Yixiao,Xu, Conghui,Wang, Doudou,Wang, Xinyu,Xu, Lijin,Li, Huanrong

, p. 12385 - 12388 (2014)

A general and efficient Rh(i)-catalyzed decarbonylative direct C2-olefination of indoles with vinyl carboxylic acids has been developed. The reaction exhibits excellent functional group tolerance, regioselectivity and stereoselectivity, giving a broad range of C2-alkenylated indoles in good to excellent yields. This journal is

Mild and efficient C2-alkenylation of indoles with alkynes catalyzed by a cobalt complex

Ding, Zhenhua,Yoshikai, Naohiko

scheme or table, p. 4698 - 4701 (2012/07/03)

Direct alkenylation of the C2-position of indoles bearing an easily removable N-pyrimidyl group with alkynes has been achieved by using a cobalt catalyst complexed with a phosphine-pyridine bidentate ligand. This reaction has wide substrate scope and is highly efficient and stereoselective at room temperature. The alkenylated indoles serve as useful platforms for further synthetic transformations (some products of these transformations are shown in the scheme). Copyright
