Check Digit Verification of cas no
The CAS Registry Mumber 22250-54-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,2,2,5 and 0 respectively; the second part has 2 digits, 5 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 22250-54:
(7*2)+(6*2)+(5*2)+(4*5)+(3*0)+(2*5)+(1*4)=70
70 % 10 = 0
So 22250-54-0 is a valid CAS Registry Number.

Derivatization of Amines with 4-Substituted 7-Nitrobenzofurazans
Heberer, H.,Kersting, H.,Matschiner, H.
, p. 487 - 504 (2007/10/02)
Electrophilic derivatives of 4-nitro-benzofurazan with different reactivities were used to synthesize 28 new mono- and disubstituted 4-amino-7-nitrobenzofurazans 2b, 2d, 2f-2i, 2l, 2m-2n, 3b-3f, 3h-3j, 4c-4d, 4f-4k, 4m, 4o-4p.A reaction mechanism is proposed on the basis of the differences of the reactivities and a preliminary kinetic examination.The acid character of the N-H-function in monosubstituted compounds is demonstrated by means of spectroscopical investigation of pKa-values.Data from i.r., u.v./vis, and fluorescence studies are offered.
