Check Digit Verification of cas no
The CAS Registry Mumber 5670-69-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,6,7 and 0 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 5670-69:
(6*5)+(5*6)+(4*7)+(3*0)+(2*6)+(1*9)=109
109 % 10 = 9
So 5670-69-9 is a valid CAS Registry Number.

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.
