49833-37-6 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 49833-37-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,9,8,3 and 3 respectively; the second part has 2 digits, 3 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 49833-37:
(7*4)+(6*9)+(5*8)+(4*3)+(3*3)+(2*3)+(1*7)=156
156 % 10 = 6
So 49833-37-6 is a valid CAS Registry Number.

Reaction of Arynes with Vinyl Sulfoxides: Highly Stereospecific Synthesis of ortho-Sulfinylaryl Vinyl Ethers

Li, Yuanming,Studer, Armido

, p. 666 - 669 (2017/02/10)

The reaction of in situ generated arynes with aryl vinyl sulfoxides provides ortho-arylsulfinylaryl vinyl ethers via aryne σ-bond insertion into the S-O-bond and concomitant stereospecific S-O-vinyl migration. The cascade allows preparing di- or trisubsti

Preparation and Reactivity of β-(tri-n-butylstannyl)acrylates

Booth, Colin,Imanieh, Hussein,Quayle, Peter,Shui-Yu, Lu

, p. 413 - 416 (2007/10/02)

The reaction of heterofunctionalised vinyl stannanes with trichloroacetyl chloride occours without ipso-substitution, and provides easy access to a variety of β-(tri-n-butylstannyl)acrylates.

β-TRIBUTYLSTANNYLACRYLATES. STEREOSPECIFIC SYNTHESIS VIA CONJUGATE ADDITON OF TRIBUTYLSTANNYLCOPPER

Seitz, David E.,Lee, Shi-Hung

, p. 4909 - 4912 (2007/10/02)

The synthesis of cis- and trans-β-tributylstannylacrylates from conjugate addition of tributylstannylcopper to various β-substituted acrylates is shown to be a highly stereospecific reaction.Of four tributylstannylmetal reagents examined for this conversion, optimum results were obtained with tributylstannylcopper.
