Check Digit Verification of cas no

The CAS Registry Mumber 88141-88-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,8,1,4 and 1 respectively; the second part has 2 digits, 8 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 88141-88:
(7*8)+(6*8)+(5*1)+(4*4)+(3*1)+(2*8)+(1*8)=152
152 % 10 = 2
So 88141-88-2 is a valid CAS Registry Number.

Synthesis of 2-(4-azulenyl)ethanamine derivatives as a nonbenzenoid analog of biogenic amine

Kurokawa

, p. 2311 - 2318 (2007/10/02)

2-(4-Azulenyl)ethanamine derivatives, nonbenzenoid analogs of the biologically active amine, were synthesized by the action of methyleneammonium salts on sodium 4-methylazulenide, sodium 4,6,8-trimethylazulenide, and sodium guaiazulenide. These compounds, as well as their hydrochlorides, were characterized by UV, IR, **1H NMR, **1**3C NMR, and MS data. The reaction of sodium guaiazulenide and N-ethylidenemethylamine also yielded the corresponding 2-(4-azulenyl)ethanamine derivatives, but the low yield of the product showed that the electrophilicity of azomethine carbon atom to 4-methylene carbanion was insufficient. The enzyme activity for some of those products was investigated. Negligible effect was found on prostaglandin 15-hydroxydehydrogenase, and considerable inhibition to cyclic AMP-phosphodiesterase, in vitro.
