86824-65-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 86824-65-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,6,8,2 and 4 respectively; the second part has 2 digits, 6 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 86824-65:
(7*8)+(6*6)+(5*8)+(4*2)+(3*4)+(2*6)+(1*5)=169
169 % 10 = 9
So 86824-65-9 is a valid CAS Registry Number.

Copper(I) iodide: A catalyst for the improved synthesis of aryl propargyl ethers
Bell,Davies,Geen,Mann
, p. 707 - 712 (2007/10/02)
Copper(I) iodide catalyses the reaction between phenols and dialkylpropargyl chlorides to give aryl 1,1-dialkylpropargyl ethers 5 a-k and 7a-e in good yields and purity. These ethers are important as precursors to the 2H-1-benzopyrans 8a-l and 9a-e.
