Check Digit Verification of cas no
The CAS Registry Mumber 342405-19-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,4,2,4,0 and 5 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 342405-19:
(8*3)+(7*4)+(6*2)+(5*4)+(4*0)+(3*5)+(2*1)+(1*9)=110
110 % 10 = 0
So 342405-19-0 is a valid CAS Registry Number.

Transition-Metal-Free Selective Iodoarylation of Pyrazoles via Heterocyclic Aryliodonium Ylides
Lu, Nannan,Huang, Liangsen,Xie, Lili,Cheng, Jiajia
, p. 3437 - 3443 (2018/07/29)
A one-pot transition-metal-free selective iodoarylation of pyrazoles with aryliodine diacetates has been developed. The reaction proceeds via the generation of NH-pyrazole-iodonium salts in situ, followed by sequential phen/K2CO3-mediated intermolecular arylation. When the iodonium ylide was directly used as substrate, the difunctionalization products could be prepared in high yield under base- and metal-free conditions. This transformation provides an efficient route to high-value multisubstituted pyrazole derivatives from simple and readily available substrates.
