Chemical Properties
Clear light brown to brown solution
Uses
Vinylmagnesium bromide solution (1 M in THF) may be used in the synthesis of 2-vinylchroman-4-ones by the conjugate addition with chromones in the presence of a Lewis acid.It may also be used in the following transformations: (S)-3-(benzyloxy)-4-oxo-butanoic acid methyl ester to methyl (3S,4S)-4-hydroxy-3-(phenylmethoxy)hex-5-enoate.(R)-1-Azido-5,6-epoxyhexane to (S)-1-(4-azidobutyl)-2-propen-1-ol.2,3-O-Isopropylidene-D-ribose to 1-[(4R,5S)-5-((1S)-1-hydroxyallyl)-2,2-dimethyl[1,3]dioxolan-4-yl]ethane-1,2-diol.(4S,5S)-2,2-Dimethyl-5-vinyl[1,3]dioxolane-4-carbaldehyde to (1R,4R,5S)- and (1S,4R,5S)-1-(2,2-dimethyl-5-vinyl[1,3]dioxolan-4-yl)prop-2-en-1-ol.Ethyl levulinate to ?-methyl-?-vinylbutyrolactone.
Check Digit Verification of cas no
The CAS Registry Mumber 1826-67-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,8,2 and 6 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1826-67:
(6*1)+(5*8)+(4*2)+(3*6)+(2*6)+(1*7)=91
91 % 10 = 1
So 1826-67-1 is a valid CAS Registry Number.
