Check Digit Verification of cas no

The CAS Registry Mumber 18771-85-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,8,7,7 and 1 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 18771-85:
(7*1)+(6*8)+(5*7)+(4*7)+(3*1)+(2*8)+(1*5)=142
142 % 10 = 2
So 18771-85-2 is a valid CAS Registry Number.

Synthesis of condensed nitrofuroxanes using hydroxylamine

Klyuchnikov,Starovoitov,Khairutdinov,Golovin

, p. 853 - 854 (2007/10/03)

The possibility of preparing condensed nitrofuroxanes using hydroxylamine was examined.

AMBIPHILIC FUROXAN RING. BENZOFUROXAN OXIDATION BY PERACID AND REDUCTION BY COPPER

Boyer, Joseph H.,Huang, Chrongbao

, p. 1233 - 1240 (2007/10/02)

Monopersulfuric acid, trifluoroperacetic acid and hydrogen peroxide in polyphosphonic acid, or with selenium dioxide in t-butyl alcohol, or in tetramethylene sulfone have each oxidized benzofuroxan into o-dinitrobenzene.Monopersulfuric acid oxidized 4-nitrobenzofuroxan into 1,2,3-trinitrobenzene (80percent) and 4,6-dinitrobenzofuroxan into 1,2,3,5-tetranitrobenzene (99percent); hydrogen peroxide in polyphosphoric acid was moderately efficient for the latter oxidation.Copper in acidified ethanol transformed 4,6-dinitrobenzofuroxan into picramide quantitatively.
