Check Digit Verification of cas no
The CAS Registry Mumber 16420-30-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,6,4,2 and 0 respectively; the second part has 2 digits, 3 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 16420-30:
(7*1)+(6*6)+(5*4)+(4*2)+(3*0)+(2*3)+(1*0)=77
77 % 10 = 7
So 16420-30-7 is a valid CAS Registry Number.

Nitrosation of aryl and heteroaryltrifluoroborates with nitrosonium tetrafluoroborate
Molander, Gary A.,Cavalcanti, Livia N.
experimental part, p. 4402 - 4413 (2012/06/18)
Organotrifluoroborates have emerged as an alternative to toxic and air- and moisture-sensitive organometallic species for the synthesis of functionalized aryl and heteroaryl compounds. It has been shown that the trifluoroborate moiety can be easily converted into a variety of different substituents in a late synthetic stage. In this paper, we disclose a mild, selective, and convenient method for the ipso-nitrosation of organotrifluoroborates using nitrosonium tetrafluoroborate (NOBF4). Aryl- and heteroaryltrifluoroborates were converted into the corresponding nitroso products in good to excellent yields. This method proved to be tolerant of a broad range of functional groups.
