Check Digit Verification of cas no
The CAS Registry Mumber 104722-13-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,4,7,2 and 2 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 104722-13:
(8*1)+(7*0)+(6*4)+(5*7)+(4*2)+(3*2)+(2*1)+(1*3)=86
86 % 10 = 6
So 104722-13-6 is a valid CAS Registry Number.

Copper catalysed preparation of vinyl ethers from unactivated vinylic halides
Keegstra
, p. 2681 - 2690 (2007/10/02)
Vinylic halides have been treated with sodium methoxide in the presence of 10 mol% of copper bromide. Most of the vinylic methyl ethers could thus be obtained in a good yield. The reaction proceeds with a 100% retention of configuration. The mechanism of
