2568-76-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 2568-76-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,5,6 and 8 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 2568-76:
(6*2)+(5*5)+(4*6)+(3*8)+(2*7)+(1*6)=105
105 % 10 = 5
So 2568-76-5 is a valid CAS Registry Number.

SYNTHESIS AND PROPERTIES OF 3,3-DISUBSTITUTED CYCLOPROPENES CONTAINING AN ALKYNYL GROUP

Ivanov, A. L.,Domnin, I. N.

, p. 2298 - 2303 (2007/10/02)

3-Methyl-3-ethynylcyclopropene, 3-methyl-3-(3,3-dimethylbutynyl)cyclopropene, and bis(1-methyl-2-cyclopropenyl)acetylene were obtained by the reaction of the corresponding alkenynes with dibromocarbene following by partial reduction of the dibromide and elimination of hydrogen bromide in the monobromide.It was shown by 13C NMR spectroscopy that the introduction of an alyknyl group in place of the methyl group at position 3 of the three-membered ring leads to an increase in the s character of the carbon atoms at the cyclopropene double bond.At elevated temperatures 3-methyl-3-ethynylcyclopropene undergoes cyclodimerization with the formation of a mixture of the following stereoisomers: 3e,6e-Dimethyl-3a,6a-diethynyl-trans-tricyclo2.4>hexane, 3e,6a-dimethyl-3a,6e-diethynyl-trans-tricyclo2.4>hexane, and 3a,6a-dimethyl-3e,6e-diethynyl-trans-tricyclo2.4>hexane.
