Check Digit Verification of cas no

The CAS Registry Mumber 1616494-83-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,6,1,6,4,9 and 4 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1616494-83:
(9*1)+(8*6)+(7*1)+(6*6)+(5*4)+(4*9)+(3*4)+(2*8)+(1*3)=187
187 % 10 = 7
So 1616494-83-7 is a valid CAS Registry Number.

Intramolecular metal-free oxidative aryl-aryl coupling: An unusual hypervalent-iodine-mediated rearrangement of 2-substituted n-phenylbenzamides

Shang, Siyun,Zhang-Negrerie, Daisy,Du, Yunfei,Zhao, Kang

, p. 6216 - 6219 (2014/06/23)

Hypervalent-iodine-mediated oxidative coupling of the two aryl groups in either 2-acylamino-N-phenyl-benzamides or 2-hydroxy-N-phenylbenzamides, with concomitant insertion of the ortho-substituted N or O atom into the tether, has been described for the first time. This unusual metal-free rearrangement reaction involves an oxidative C(sp2)?C(sp2) aryl-aryl bond formation, cleavage of a C(sp2)?C(O) bond, and a lactamization/lactonization. Furthermore, unsymmetrical diaryl compounds can be easily obtained by removing the tether within the cyclized product.
