Check Digit Verification of cas no

The CAS Registry Mumber 31100-22-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,1,1,0 and 0 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 31100-22:
(7*3)+(6*1)+(5*1)+(4*0)+(3*0)+(2*2)+(1*2)=38
38 % 10 = 8
So 31100-22-8 is a valid CAS Registry Number.

Cu(II)-mediated C-H amidation and amination of arenes: Exceptional compatibility with heterocycles

Shang, Ming,Sun, Shang-Zheng,Dai, Hui-Xiong,Yu, Jin-Quan

supporting information, p. 3354 - 3357 (2014/03/21)

A Cu(OAc)2-mediated C-H amidation and amination of arenes and heteroarenes has been developed using a readily removable directing group. A wide range of sulfonamides, amides, and anilines function as amine donors in this reaction. Heterocycles present in both reactants are tolerated, making this a broadly applicable method for the synthesis of a family of inhibitors including 2-benzamidobenzoic acids and N-phenylaminobenzoates.
