Check Digit Verification of cas no

The CAS Registry Mumber 1067249-68-6 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,6,7,2,4 and 9 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1067249-68:
(9*1)+(8*0)+(7*6)+(6*7)+(5*2)+(4*4)+(3*9)+(2*6)+(1*8)=166
166 % 10 = 6
So 1067249-68-6 is a valid CAS Registry Number.

Facile synthesis of 2-bromoindoles by ligand-free CuI-catalyzed intramolecular cross-coupling of gem-dibromoolefins

Jiang, Baishan,Tao, Kemei,Shen, Wang,Zhang, Jiancun

experimental part, p. 6342 - 6344 (2011/01/04)

A mild and efficient synthesis of 2-bromoindoles by ligand-free CuI-catalyzed intramolecular cross-coupling of gem-dibromoolefins was developed. Reactions were carried out in toluene at room temperature and the corresponding 2-bromoindoles were obtained in excellent yields.
