Check Digit Verification of cas no
The CAS Registry Mumber 163333-05-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,3,3,3 and 3 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 163333-05:
(8*1)+(7*6)+(6*3)+(5*3)+(4*3)+(3*3)+(2*0)+(1*5)=109
109 % 10 = 9
So 163333-05-9 is a valid CAS Registry Number.

Alkynylcubanes as precursors of rigid-rod molecules and alkynylcyclooctatetraenes
Eaton, Philip E.,Galoppini, Elena,Gilardi, Richard
, p. 7588 - 7596 (2007/10/02)
We have developed new methodology for the synthesis of alkynylcubanes and have used these compounds to make rigid-rod molecules constructed of cubane and acetylene subunits. Terminal and substituted alkynylcubanes 7a, 7b, 8a, 8b, 12a, and 12b were synthes
