Check Digit Verification of cas no
The CAS Registry Mumber 53866-33-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,3,8,6 and 6 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 53866-33:
(7*5)+(6*3)+(5*8)+(4*6)+(3*6)+(2*3)+(1*3)=144
144 % 10 = 4
So 53866-33-4 is a valid CAS Registry Number.

Shifted Selectivity in Protonation Enables the Mild Deuteration of Arenes through Catalytic Amounts of Bronsted Acids in Deuterated Methanol
Fischer, Oliver,Hubert, Anja,Heinrich, Markus R.
, p. 11856 - 11866 (2020/10/23)
Taking advantage of the "differentiating effect"of the solvent methanol, deuterations of electron-rich aromatic systems can be carried out under mild acid catalysis and thus under far milder conditions than known so far. The exceptional functional group t
