Check Digit Verification of cas no

The CAS Registry Mumber 1280203-63-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,8,0,2,0 and 3 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1280203-63:
(9*1)+(8*2)+(7*8)+(6*0)+(5*2)+(4*0)+(3*3)+(2*6)+(1*3)=115
115 % 10 = 5
So 1280203-63-5 is a valid CAS Registry Number.

Sterically Congested 2,6-Disubstituted Anilines from Direct C?N Bond Formation at an Iodine(III) Center

Lucchetti, Nicola,Scalone, Michelangelo,Fantasia, Serena,Mu?iz, Kilian

, p. 13335 - 13339 (2016)

2,6-Disubstituted anilines are readily prepared from the direct reaction between amides and diaryliodonium salts. As demonstrated for 24 different examples, the reaction is of unusually broad scope with respect to the sterically congested arene and the nitrogen source, occurs without the requirement for any additional promoter, and proceeds through a direct reductive elimination at the iodine(III) center. The efficiency of the coupling procedure is further demonstrated within the short synthesis of a chemerin binding inhibitor.
