Check Digit Verification of cas no

The CAS Registry Mumber 53330-30-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,3,3,3 and 0 respectively; the second part has 2 digits, 3 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 53330-30:
(7*5)+(6*3)+(5*3)+(4*3)+(3*0)+(2*3)+(1*0)=86
86 % 10 = 6
So 53330-30-6 is a valid CAS Registry Number.

Amine basicities in benzene and in water

Frenna, Vincenzo,Vivona, Nicolo,Consiglio, Giovanni,Spinelli, Domenico

, p. 1865 - 1868 (1985)

The constants for ion-pair formation with 2,4-dinitrophenol in benzene (KB), the pKa values in water, of thirty-three amines have been measured.According to the class of amine, two different situations can be observed: for primary amines and secundery cyclic amines, the effects of structural variations on basicity are higher in water than in benzene; on the other hand, for tertiary amines these effects are similar in the two solvents.KB Values of primary amines give a good correlation with ? *.The Tatf and Hancock equation allows a unifying treatment of KB values of the various classes of amines.
