Check Digit Verification of cas no
The CAS Registry Mumber 21720-68-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,1,7,2 and 0 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 21720-68:
(7*2)+(6*1)+(5*7)+(4*2)+(3*0)+(2*6)+(1*8)=83
83 % 10 = 3
So 21720-68-3 is a valid CAS Registry Number.

2,5-Diarylamino-N-α(β)-naphthyl-1,4-benzoquinone monoimines undergo oxidative cyclization to give benzannelated phenazinone derivatives.The effect of an N-aryl fragment on the ease of cyclization decreases in the order N-β-naphthyl > N-α-naphthyl > N-phenyl. 2-Arylamino-N-phenyl-1,4-naphthoquinone monoimines do not undergo oxidative cyclization to phenazinones.

Comparison is made between products obtained by oxidation of N-phenyl-1-naphthylamines and 1-naphthyl phenyl nitroxides with peroxyl radicals.It is concluded that oxidation of the amines does not proceed to a considerable extent via the nitroxides.Comparison is also made of products obtained from these amines and nitroxides by oxidation with Fremy's salt.
