Check Digit Verification of cas no

The CAS Registry Mumber 1469991-11-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,6,9,9,9 and 1 respectively; the second part has 2 digits, 1 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1469991-11:
(9*1)+(8*4)+(7*6)+(6*9)+(5*9)+(4*9)+(3*1)+(2*1)+(1*1)=224
224 % 10 = 4
So 1469991-11-4 is a valid CAS Registry Number.

Intramolecular Aryl Migration of Diaryliodonium Salts: Access to ortho-Iodo Diaryl Ethers

Chen, Huangguan,Han, Jianwei,Wang, Limin

, p. 12313 - 12317 (2018/09/10)

By using vicinal trifluoromethanesulfonate-substituted diaryliodonium salts, a novel approach was developed for the synthesis of ortho-iodo diaryl ethers by intramolecular aryl migration. The reaction conditions are mild with a broad substrate scope. Mechanistic insight suggests a sulfonyl-directed nucleophilic aromatic substitution pathway. Additionally, the product ortho-iodo diaryl ethers serve as versatile synthons as demonstrated with several coupling reactions. Furthermore, a useful thyroxine analogue of the 3-iodo-l-thyronine (3-T1) derivative was synthesized by this aryl migration procedure.
