Check Digit Verification of cas no

The CAS Registry Mumber 89464-07-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,9,4,6 and 4 respectively; the second part has 2 digits, 0 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 89464-07:
(7*8)+(6*9)+(5*4)+(4*6)+(3*4)+(2*0)+(1*7)=173
173 % 10 = 3
So 89464-07-3 is a valid CAS Registry Number.

Nitrocarbons. 4. Reaction of Polynitrobenzenes with Hydrogen Halides. Formation of Polynitrohalobenzenes

Nielsen, Arnold T.,Chafin, Andrew P.,Christian, Stephen L.

, p. 4575 - 4580 (2007/10/02)

Hexanitrobenzene and pentanitrobenzene in benzene solution react with hydrogen halides (HCl, HBr, HI, but not HF) at 25 deg C to produce high yields of pentanitrohalobenzenes and 2,3,4,6-tetranitrohalobenzenes, respectively.Pentanitrofluorobenzene also reacts readily with HCl to yield 3-chloro-2,4,5,6-tetranitrofluorobenzene, but the other pentanitrohalobenzenes are much less reactive. 1,2,3,5- and 1,2,4,5-tetranitrobenzenes react rapidly with concentrated hydrochloric or hydrobromic acids at reflux to form picryl halides and 1-halo-2,4,5-trinitrobenzenes, respectively; pentanitrotoluene reacts very slowly under these conditions to form 3-halo-2,4,5,6-tetranitrotoluenes in lower yields.The scope and limitations of this regioselective reaction are defined, and comparison is made to related reactions.A mechanism is presented and discussed.
