Check Digit Verification of cas no

The CAS Registry Mumber 100990-66-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,0,9,9 and 0 respectively; the second part has 2 digits, 6 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 100990-66:
(8*1)+(7*0)+(6*0)+(5*9)+(4*9)+(3*0)+(2*6)+(1*6)=107
107 % 10 = 7
So 100990-66-7 is a valid CAS Registry Number.

Para -Selective copper-catalyzed C(sp2)-H amidation/dimerization of anilides via a radical pathway

Viveki, Amol B.,Garad, Dnyaneshwar N.,Gonnade, Rajesh G.,Mhaske, Santosh B.

supporting information, p. 1565 - 1568 (2020/02/13)

Copper-catalyzed amidation/dimerization of anilides via regioselective C(sp2)-H functionalization is achieved. The para-selective amidation is accomplished on the anilide aromatic ring via a radical pathway leading to C-N bond formation in the presence of ammonium persulfate as a radical source/oxidant for the copper catalyst. The developed protocol tolerates a wide range of anilide substrates. The regioselectivity is confirmed by single-crystal X-ray studies.
