Check Digit Verification of cas no
The CAS Registry Mumber 3731-39-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,7,3 and 1 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 3731-39:
(6*3)+(5*7)+(4*3)+(3*1)+(2*3)+(1*9)=83
83 % 10 = 3
So 3731-39-3 is a valid CAS Registry Number.

Any liquid azo dyes, in which auxochrome such as dialkylamino, alkoxy, and amino group is attached in a molecule, were produced. In a series of 2-alkyl-4'-(dimethylamino)azobenzenes, the butyl, hexyl, octyl, and dodecyl derivatives were liquid at room temperature, whereas the propyl, 1-methylethyl, 1-methylpropyl, 1,1-dimethylethyl, and octadecyl derivatives were solid. Thus, it is essential for liquid azo dyes to have a medium n-alkyl group at the 2-position. In a series of 2-butyl-4'-(dialkylamino)azobenzenes, the dimethylamino, diethylamino, dibutylamino, dioctylamino, and didodecylamino derivatives were liquid. 2-Butyl-4'-methoxyazobenzene and 4-amino-3,5-dimethyl-2'-butylazobenenzne were also liquid, whereas 2-butyl-4'-hydroxyazobenznene, 4-amino-2'-butylazobenzene, and 2-butyl-4'-(methylamino)azobenzene were solid. The prevention of π/π stacking, alkyl-alkyl interactions, and intermolecular hydrogen bond could produce liquid azo dyes.
