Check Digit Verification of cas no

The CAS Registry Mumber 97462-22-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,7,4,6 and 2 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 97462-22:
(7*9)+(6*7)+(5*4)+(4*6)+(3*2)+(2*2)+(1*2)=161
161 % 10 = 1
So 97462-22-1 is a valid CAS Registry Number.

Isoquinolinium N-arylimides and trans-cyclooctenes

Huisgen, Rolf,Palacios-Gambra, Francisco,Polborn, Kurt,Boeckh, Dieter

, p. 353 - 364 (2007/10/03)

The inertness of isoquinolinium N-arylimides (5a,b) versus common cycloalkenes is overcome by the highly reactive (E)-cyclooctene and (E,Z)- 1,5-cyclooctadiene. NMR spectra and an X-Ray analysis established the retention of dipolarophile configuration in the cycloadducts (7a,b) and (9a,b) which were obtained in > 90% yield. Acid-base catalysis effects the opening of the pyrazolidine ring by β-elimination; the products are 1- [trans-2-arylaminocyclooctyl]isoquinolines (8,10).
