Check Digit Verification of cas no

The CAS Registry Mumber 2721-93-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,7,2 and 1 respectively; the second part has 2 digits, 9 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 2721-93:
(6*2)+(5*7)+(4*2)+(3*1)+(2*9)+(1*3)=79
79 % 10 = 9
So 2721-93-9 is a valid CAS Registry Number.

Ru-Catalyzed C(sp2)?H Bond Arylation of Benzamides Bearing a Novel 4-Aminoantipyrine as a Directing Group

A novel design-based removable N,O-bidentate directing group based on cheap and commercially available 4-aminoantipyrine (AAP) is reported. Aromatic AP amides bearing 4-aminoantipyrine underwent efficient Ru-catalyzed C(sp2)?H arylation using [RuCl2(PPh3)3] as a catalyst and aryl bromides as electrophiles. The novel bidentate directing group enabled the C?H functionalization reaction with good scope, good functional group tolerance and in decent yields.
