Check Digit Verification of cas no
The CAS Registry Mumber 156329-80-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,6,3,2 and 9 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 156329-80:
(8*1)+(7*5)+(6*6)+(5*3)+(4*2)+(3*9)+(2*8)+(1*0)=145
145 % 10 = 5
So 156329-80-5 is a valid CAS Registry Number.

Formation and reactions of bicyclo[1.1.1]pentyl-1 cations
Wiberg, Kenneth B.,McMurdie, Neil
, p. 11990 - 11998 (2007/10/03)
The ionization of 1-bicyclo[1.1.1]pentyl halides was shown to initially form the 1,3-bridged bicyclo[1.1.1]pentyl-l cation. It appears to be a transition state that leads to the bicyclo[1.1.0]butyl-1-carbinyl cation which can be trapped with azide ion and
