Check Digit Verification of cas no

The CAS Registry Mumber 1068653-72-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,6,8,6,5 and 3 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1068653-72:
(9*1)+(8*0)+(7*6)+(6*8)+(5*6)+(4*5)+(3*3)+(2*7)+(1*2)=174
174 % 10 = 4
So 1068653-72-4 is a valid CAS Registry Number.

A gold(I)-catalyzed intramolecular reaction of propargylic/homopropargylic alcohols with oxirane

Dai, Lun-Zhi,Shi, Min

scheme or table, p. 7011 - 7018 (2009/08/12)

The gold(I)-catalyzed cycloisomerization of epoxy alkynes in the presence of a nucleophile is an efficient protocol to provide ketal skeletons with high stereoselectivity. An intramolecular reaction of propargylic/homopropargylic alcohols with oxirane to produce ketal/spiroketals in moderate yields under mild conditions has been reported. Moreover, the mechanism of this kind of reaction has been discussed on the basis of a series of control and 18O tracer experiments.
