Check Digit Verification of cas no

The CAS Registry Mumber 157948-87-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,7,9,4 and 8 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 157948-87:
(8*1)+(7*5)+(6*7)+(5*9)+(4*4)+(3*8)+(2*8)+(1*7)=193
193 % 10 = 3
So 157948-87-3 is a valid CAS Registry Number.

Zirconocene-mediated synthesis of 3,4-disubstituted piperidines and reduced isoquinolines

Kemp, Mark I.,Whitby, Richard J.,Coote, Steven J.

, p. 557 - 568 (2007/10/03)

Intramolecular cocyclisation of 4-azaocta-1,7-dienes, -1-en-7-ynes, -7- en-1-ynes and -1,7-diynes using 'zirconocene' equivalents affords 3-aza-8- zirconabicyclo[4.3.0]nonanes, -6-enes, -9-enes or -6,9-dienes. Protonolysis, iodinolysis, or carbonylation of these complexes affords 3,4-disubstitued piperidines. Exocyclic 1,3-dienes formed from the coupling/protonolysis of 4- azaocta-1,7-diynes react with activated dienophiles to yield reduced isoquinolines.
