Check Digit Verification of cas no

The CAS Registry Mumber 1607804-22-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,6,0,7,8,0 and 4 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1607804-22:
(9*1)+(8*6)+(7*0)+(6*7)+(5*8)+(4*0)+(3*4)+(2*2)+(1*2)=157
157 % 10 = 7
So 1607804-22-7 is a valid CAS Registry Number.

An alternative to the Sandmeyer approach to aryl iodides

Hu, Bao,Miller, William H.,Neumann, Kiel D.,Linstad, Ethan J.,DiMagno, Stephen G.

, p. 6394 - 6398 (2015)

Iodoarenes are important synthons for a wide range of organic transformations. Here we report a general strategy to prepare singly iodinated electron-rich aromatic compounds through the intermediacy of diaryliodonium salts. This process, which incorporates a phase separation that greatly simplifies product purification, is an attractive replacement for the Sandmeyer approach to iodoarenes that are otherwise difficult to access.
