Check Digit Verification of cas no

The CAS Registry Mumber 221067-99-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,1,0,6 and 7 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 221067-99:
(8*2)+(7*2)+(6*1)+(5*0)+(4*6)+(3*7)+(2*9)+(1*9)=108
108 % 10 = 8
So 221067-99-8 is a valid CAS Registry Number.

Metal-free regioselective nitration of quinoxalin-2(1H)-ones withtert-butyl nitrite

supporting information, p. 10554 - 10559 (2021/12/27)

A metal-free coupling of quinoxalin-2(1H)-ones withtert-butyl nitrite has been developed. Distinctly from the previous functionalization of quinoxalin-2(1H)-ones, this nitration reaction took place selectively at the C7 or C5 position of the phenyl ring, affording a series of 7-nitro and 5-nitro quinoxalin-2(1H)-ones in moderate to good yields. Preliminary mechanistic studies revealed that the reaction may involve a radical process.
