Check Digit Verification of cas no

The CAS Registry Mumber 109394-58-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,9,3,9 and 4 respectively; the second part has 2 digits, 5 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 109394-58:
(8*1)+(7*0)+(6*9)+(5*3)+(4*9)+(3*4)+(2*5)+(1*8)=143
143 % 10 = 3
So 109394-58-3 is a valid CAS Registry Number.

Para-Selective C-H Amidation of Simple Arenes with Nitriles

supporting information, p. 3435 - 3440 (2016/01/25)

A para-selective C-H amidation of simple arenes with nitriles has been developed. By increasing the amount of arenes, a further meta-selective C-H arylation of the produced amides occurred. Both steric and electronic effects are utilized to control the selectivity, resulting in only para-selective amidation products. The readily available nitriles as amidation reagents instead of amides makes the synthesis of N-arylamides more accessible.
