Check Digit Verification of cas no

The CAS Registry Mumber 1233340-90-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,3,3,3,4 and 0 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1233340-90:
(9*1)+(8*2)+(7*3)+(6*3)+(5*3)+(4*4)+(3*0)+(2*9)+(1*0)=113
113 % 10 = 3
So 1233340-90-3 is a valid CAS Registry Number.

Platinum-catalyzed cycloisomerization of 1,4-enynes via activation of a sp3-hybridized C-H bond

Vasu, Dhananjayan,Das, Arindam,Liu, Rai-Shung

supporting information; experimental part, p. 4115 - 4117 (2010/08/22)

We report the cycloisomerization of 1-alkenyl-1-alkynylcyclopropanes to cyclooctatriene products catalyzed by PtCl2/CO in hot xylene. In contrast to the reported enyne cycloisomerization, this 1,4-enyne cycloisomerization proceeds via an atypical addition of the allyl carbon to the alkyne in a 6-endo-dig cyclization.
