Check Digit Verification of cas no

The CAS Registry Mumber 88140-46-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,8,1,4 and 0 respectively; the second part has 2 digits, 4 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 88140-46:
(7*8)+(6*8)+(5*1)+(4*4)+(3*0)+(2*4)+(1*6)=139
139 % 10 = 9
So 88140-46-9 is a valid CAS Registry Number.

Synthesis of 4,6-Dinitrobenzofurazan, a New Electron-Deficient Aromatic

Read, Roger W.,Spear, Robert J.,Norris, William P.

, p. 1227 - 1237 (2007/10/02)

Preparation of 4,6-dinitrobenzofurazan (6) has been investigated by a number of routes.Its synthesis from 4,6-dinitrobenzofuroxan (4,6-dinitrobenzofurazan 1-oxide) (1) by reduction with triphenylphosphine proceeds in similar overall yield to the known method of nitration of 5-nitrobenzofurazan (8) but in fewer steps.Nitration of 4-nitrobenzofurazan (7) was studied as an alternative route, and the difference in reactivity between (7) and (8) is discussed.The benzofurazan (6) readily forms hydroxy and methoxy Meisenheimer complexes which have been isolated as stable, but highly explosive, potassium salts.
