143799-42-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 143799-42-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,3,7,9 and 9 respectively; the second part has 2 digits, 4 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 143799-42:
(8*1)+(7*4)+(6*3)+(5*7)+(4*9)+(3*9)+(2*4)+(1*2)=162
162 % 10 = 2
So 143799-42-2 is a valid CAS Registry Number.

Practical synthesis of (Z)-polyaromatic and heteroaromatic vinylacetylenes

Hayford, Anthony,Kaloko Jr., Joseph,El-Kazaz, Salwa,Bass, Gwen,Harrison, Cheryl,Corprew, Thomas

, p. 2671 - 2673 (2007/10/03)

(Chemical Equation Presented) Two synthetic routes to several (Z)-polyaromatic and heteroaromatic substituted vinylacetylenes are described. The nature of aryl- or heteroaryl-substituted carboxaldehyde used as starting material dictated the choice of Wittig salt employed. A very attractive way to construct polyaromatic and pyridine-containing enynes is the reaction of polyaromatic and pyridine-containing aldehydes with bromomethyltriphenylphosphonium bromide in the presence of potassium tert-butoxide followed by a Sonogashira desilylation procedure (method B).

A stereoselective synthesis of 1-phenyl-1-buten-3-yne and some 1-heteroaryl analogues

Fossatelli, Marco,Van Der Kerk, Anca C. T. H. M.,Vasilevsky, Sergei F.,Brandsma, Lambert

, p. 4229 - 4232 (2007/10/02)

Z-Enynes, RCH=CHC≡CH (R= phenyl, 2-furyl, 2- and 3-thienyl and 3-pyridyl) can be obtained in ～ 40% overall yields and with a stereoselectivity of> 95% by Pd/Cu-catalyzed cross-coupling of the readily available enyne sulfide HC≡CCH=CHSC2H5
