Check Digit Verification of cas no
The CAS Registry Mumber 2199-70-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,1,9 and 9 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 2199-70:
(6*2)+(5*1)+(4*9)+(3*9)+(2*7)+(1*0)=94
94 % 10 = 4
So 2199-70-4 is a valid CAS Registry Number.

Perdeuteration of Deactivated Aryl Halides by H/D Exchange under Superelectrophile Catalysis
He, Tao,Klare, Hendrik F. T.,Oestreich, Martin
supporting information, p. 4734 - 4738 (2022/03/27)
Superelectrophilic silylium/arenium ions are shown to be highly effective H/D exchange promoters for the exhaustive deuteration of electron-deficient aryl halides. Several of the resulting perdeuterated aryl halides have been previously inaccessible with existing deuterium-labeling procedures. Using inexpensive C6D6as the deuterium source, excellent degrees of deuterium incorporation were achieved under ambient reaction conditions. Importantly, the perdeuteration remains unaffected on multigram scale, even at a reduced catalyst loading of 0.1 mol %. By this method, otherwise expensive or noncommercially available NMR solvents such as 1,2-dichloro- and 1,2-difluorobenzene can be prepared.
