Check Digit Verification of cas no

The CAS Registry Mumber 683246-82-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,8,3,2,4 and 6 respectively; the second part has 2 digits, 8 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 683246-82:
(8*6)+(7*8)+(6*3)+(5*2)+(4*4)+(3*6)+(2*8)+(1*2)=184
184 % 10 = 4
So 683246-82-4 is a valid CAS Registry Number.

Copper-mediated selective cross-coupling of 1,1-dibromo-1-alkenes and heteronucleophiles: Development of general routes to heterosubstituted alkynes and alkenes

Jouvin, Kevin,Coste, Alexis,Bayle, Alexandre,Legrand, Frederic,Karthikeyan, Ganesan,Tadiparthi, Krishnaji,Evano, Gwilherm

, p. 7933 - 7947 (2013/01/16)

Efficient and general procedures for the cross-coupling of 1,1-dibromoalkenes and N-, O-, and P-nucleophiles are reported. Fine-tuning of the reaction conditions allows for either site-selective, double, or alkynylative cross-coupling, therefore providing

Synthesis of 1,2-amino alcohols by sigmatropic rearrangements of 3-(N-Tosylamino)allylic alcohol derivatives

Barbazanges, Marion,Meyer, Christophe,Cossy, Janine,Turner, Peter

scheme or table, p. 4480 - 4495 (2011/06/24)

Sigmatropic rearrangements of 3-(N-tosylamino)allylic alcohol derivatives, a particular subclass of functionalized enamides, have been investigated. Whereas the presence of the nitrogen atom alters the stereochemical outcome of Ireland-Claisen rearrangeme

Stereoselective synthesis of 1,2-aminoalcohols by [2,3]-wittig rearrangements

Barbazanges, Marion,Meyer, Christophe,Cossy, Janine

, p. 3245 - 3248 (2008/02/12)

[2,3]-Wittig rearrangements of (E)-3-aza-allylic alcohol derivatives can provide access to functionalized 1,2-aminoalcohols with high syn or anti diastereoselectivity depending on the anionic stabilizing group (amide or alkyne). American Chemical Society.

Copper sulfate-pentahydrate-1,10-phenanthroline catalyzed amidations of alkynyl bromides. Synthesis of heteroaromatic amine substituted ynamides

Zhang, Yanshi,Hsung, Richard P.,Tracey, Michael R.,Kurtz, Kimberly C. M.,Vera, Eymi L.

, p. 1151 - 1154 (2007/10/03)

(Equation presented) A practical cross-coupling of amides with alkynyl bromides using catalytic CuSO4·5H2O and 1,10-phenanthroline is described here. This catalytic protocol is more environmentally friendly than the use of CuCN or copper halides and provides a general entry for syntheses of ynamides including various new sulfonyl and heteroaromatic amine substituted ynamides. Given the interest in ynamides, this N-alkynylation of amides should be significant for the future of ynamides in organic synthesis.
