Check Digit Verification of cas no
The CAS Registry Mumber 86934-41-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,6,9,3 and 4 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 86934-41:
(7*8)+(6*6)+(5*9)+(4*3)+(3*4)+(2*4)+(1*1)=170
170 % 10 = 0
So 86934-41-0 is a valid CAS Registry Number.

LITHIATED 2-ALKYNYL-1,3-DIOXANES AS FULLY OXYGENATED ACYL-ANION EQUIVALENTS: SYNTHESIS OF 1-ALKYNYL KETONES

, p. 3073 - 3082 (1983)
2-Lithio-2-(trimethylsilylethynyl)-1,3-dioxane 3 is prepared from 2-(trimethylsilylethynyl)-1,3-dioxane with n-BuLi.Alkylation of 3 produces propargylic ketals 2 exclusively.Reaction with group IV-B chlorotrimethylmetalanes gives both propargylic products 2 and allenes 6 depending on the solvent used.Desilylation of 2 as well as hydrolysis to the alkynyl ketones 1 can be carried out under mild conditions.The first 1-alkynyl stannyl ketone has been prepared in this way.Formation of 2-lithio-2-(3,3-dimethyl-1-butynyl)-1,3-dioxane 10 requires t-BuLi.With various electrophiles 10 yields propargylic products and/or allenes in ratios depending on the solvent used.
