Check Digit Verification of cas no
The CAS Registry Mumber 98545-68-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,8,5,4 and 5 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 98545-68:
(7*9)+(6*8)+(5*5)+(4*4)+(3*5)+(2*6)+(1*8)=187
187 % 10 = 7
So 98545-68-7 is a valid CAS Registry Number.

Electrochemical Nitration with Nitrite
Blum, Stephan P.,Nickel, Christean,Sch?ffer, Lukas,Karakaya, Tarik,Waldvogel, Siegfried R.
, p. 4936 - 4940 (2021/10/25)
Aromatic nitration has tremendous importance in organic chemistry as nitroaromatic compounds serve as versatile building blocks. This study represents the electrochemical aromatic nitration with NBu4NO2, which serves a dual role as supporting electrolyte and as a safe, readily available, and easy-to-handle nitro source. Stoichiometric amounts of 1,1,1-3,3,3-hexafluoroisopropan-2-ol (HFIP) in MeCN significantly increase the yield by solvent control. The reaction mechanism is based on electrochemical oxidation of nitrite to NO2, which initiates the nitration reaction in a divided electrolysis cell with inexpensive graphite electrodes. Overall, the reaction is demonstrated for 20 examples with yields of up to 88 %. Scalability is demonstrated by a 13-fold scale-up.
