624-66-8 Usage
General Description
1-Propyn-1-yl iodide, also known as propargyl iodide or 3-iodopropyne, is a chemical compound with the molecular formula C3H3I. It is an organoiodine compound used as a building block in organic synthesis, specifically in the preparation of alkynes and alkenes. The compound is clear yellow to brown liquid with a pungent odor, which should be handled carefully due to its toxic, corrosive and potentially harmful effects. Moreover, 1-propyn-1-yl iodide is sensitive to light, heat, and moisture, thus it needs to be stored in a cool, dry, and well-ventilated place away from ignition sources and strong oxidizing agents. It is important to wear appropriate personal protection when handling this chemical.
Check Digit Verification of cas no
The CAS Registry Mumber 624-66-8 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 6,2 and 4 respectively; the second part has 2 digits, 6 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 624-66:
(5*6)+(4*2)+(3*4)+(2*6)+(1*6)=68
68 % 10 = 8
So 624-66-8 is a valid CAS Registry Number.

Synthesis of stereoisomers of artemisia and chrysanthemum bis(acetylenic) enol ether spiroacetals
Wu, Boshen,Feast, George C.,Thompson, Amber L.,Robertson, Jeremy
, p. 10623 - 10630 (2012)
An 11-step synthesis is described of two diastereomeric candidates for a bis(acetylenic) enol ether spiroacetal isolated from Chrysanthemum boreale. Key steps in the synthetic route include spiroacetal lactone alkylidenation and subseqent modified Cadiota-Chodkiewicz cross-coupling to install the bis(acetylenic) enol ether functionality. From NMR comparisons, neither of the candidates, whose structures were confirmed by single-crystal X-ray diffraction, correspond to the natural product, and a proposal for the correct structure is put forward.
