Check Digit Verification of cas no

The CAS Registry Mumber 98398-26-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,8,3,9 and 8 respectively; the second part has 2 digits, 2 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 98398-26:
(7*9)+(6*8)+(5*3)+(4*9)+(3*8)+(2*2)+(1*6)=196
196 % 10 = 6
So 98398-26-6 is a valid CAS Registry Number.

Chemistry of dicationic electrophiles: superacid-catalyzed reactions of amino acetals.

Klumpp, Douglas A,Sanchez Jr., Gregorio V,Aguirre, Sharon L,Zhang, Yun,de Leon, Sarah

, p. 5028 - 5031 (2002)

Amino acetals are shown to form highly electrophilic systems in Bronsted superacids. It is proposed that amino acetals give dicationic electrophiles, and this proposal is supported by the direct observation of a dication by low-temperature (13)C NMR. When reacted with C(6)H(6) and superacidic CF(3)SO(3)H, amino acetals are shown to provide 1-(3,3-diphenylpropyl)amines and 1-(2,2-diphenylethyl)amines as condensation products in good yields (50-99%).
