Check Digit Verification of cas no
The CAS Registry Mumber 6342-57-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,3,4 and 2 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 6342-57:
(6*6)+(5*3)+(4*4)+(3*2)+(2*5)+(1*7)=90
90 % 10 = 0
So 6342-57-0 is a valid CAS Registry Number.

Halogenated Epoxides. 61. Reactions of Selected Chlorooxiranes with Sodium Methoxide: About the Question of Acetylenic and Allenic Epoxides as Intermediates
Griesbaum, Karl,Lie, Giu Oan,Keul, Helmut
, p. 679 - 682 (2007/10/02)
Reactions of sodium methoxide with five chlorooxiranes (1, 3, 11, 18, and 19) and with the corresponding isomeric chlorocarbonyl compounds have been examined.In two cases the chlorooxirane and the corresponding chlorocarbonyl compound afforded the same products, however, in different yields.In the other cases the chlorooxiranes and the corresponding chlorocarbonyl compounds gave different products.It is concluded that chlorocarbonyl compounds are not formed to a large extent as intermediates.In the reactions of two chlorooxiranes (18 and 19) with sodium methoxide, acetylenic and allenic epoxides may be invoked as transient intermediates.
