Check Digit Verification of cas no

The CAS Registry Mumber 189502-86-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,9,5,0 and 2 respectively; the second part has 2 digits, 8 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 189502-86:
(8*1)+(7*8)+(6*9)+(5*5)+(4*0)+(3*2)+(2*8)+(1*6)=171
171 % 10 = 1
So 189502-86-1 is a valid CAS Registry Number.

Isolation of a nonicosahedral intermediate in the isomerization of an icosahedral metallacarborane

Dunn,Rosair,Thomas,Weller,Welch

, p. 645 - 647 (2007/10/03)

After more than 30 years of speculation on the mechanism of the isomerization of icosahedral carboranes and their analogues, isolation of 1- provides the first clue. This intermediate has an unprecendented, dosed, nonicosahedral structure. [Mo] = [Mo(η3-C3H5)CO)2].
