Check Digit Verification of cas no

The CAS Registry Mumber 1393585-87-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,9,3,5,8 and 5 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1393585-87:
(9*1)+(8*3)+(7*9)+(6*3)+(5*5)+(4*8)+(3*5)+(2*8)+(1*7)=209
209 % 10 = 9
So 1393585-87-9 is a valid CAS Registry Number.

Metal- and ligand-free Ullmann-type C-O and C-N coupling reactions promoted by potassium tert-butoxide

Yang, Shuliang,Wu, Cunqi,Ruan, Mingbo,Yang, Yanqin,Zhao, Yongxia,Niu, Jiajia,Yang, Wei,Xu, Jingwei

, p. 4288 - 4292 (2012)

A simple, metal- and ligand-free procedure for the Ullmann-type C-O coupling reactions has been achieved by allowing aryl bromides to react with a variety of phenols in the presence of t-BuOK. Moderate to excellent yields of O-arylation products are obtained under mild conditions in a short time. In addition, two examples of C-N coupling reactions are also reported. A benzyne mechanism is proposed according to the experiment data.
