Check Digit Verification of cas no

The CAS Registry Mumber 25703-57-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,5,7,0 and 3 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 25703-57:
(7*2)+(6*5)+(5*7)+(4*0)+(3*3)+(2*5)+(1*7)=105
105 % 10 = 5
So 25703-57-5 is a valid CAS Registry Number.

A 1-norbornene adduct of a transition metal and an electrochemical study of the bridgehead olefin complex

Jones, Gavin D.,Vicic, David A.

, p. 3821 - 3823 (2005)

Treatment of a slurry of (PCy3)2NiCl2 in pentane with 1-norbornyllithium did not lead to the expected bis(1-norbornyl) nickel complex but instead led to formation of a 1-norbornene adduct, which has been structurally characterized. The X-ray data and the electrochemistry of the 1-norbornene complex suggest a metallacyclopropane extreme of olefin binding, stemming from the highly reactive nature of the bridgehead double bond.
