Check Digit Verification of cas no

The CAS Registry Mumber 1447966-72-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,4,7,9,6 and 6 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1447966-72:
(9*1)+(8*4)+(7*4)+(6*7)+(5*9)+(4*6)+(3*6)+(2*7)+(1*2)=214
214 % 10 = 4
So 1447966-72-4 is a valid CAS Registry Number.

Rh(iii)-Catalyzed regioselective mono- and di-iodination of azobenzenes using alkyl iodide

Li, Jixing,Cong, Wenxia,Gao, Zeng,Zhang, Jinlong,Yang, Huameng,Jiang, Gaoxi

, p. 3479 - 3486 (2018/05/23)

A new approach for highly regioselective iodination of azobenzenes with alkyl iodide as the iodinating reagent enabled by Rh-catalyzed oxidative C-H activation has been developed. By changing the oxidant, various mono- and di-iodinated azobenzenes were smoothly obtained in moderate to excellent yields, respectively. The preliminary mechanistic study reveals that the reaction process might undergo electrophilic substitution of the directed ortho metalated five-membered rhodacycle compound by an iodine cationic species generated in situ from alkyl iodide and oxidant.
