Check Digit Verification of cas no

The CAS Registry Mumber 6538-16-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,5,3 and 8 respectively; the second part has 2 digits, 1 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 6538-16:
(6*6)+(5*5)+(4*3)+(3*8)+(2*1)+(1*6)=105
105 % 10 = 5
So 6538-16-5 is a valid CAS Registry Number.

Nickel-Catalyzed Stereospecific C?H Coupling of Benzamides with Epoxides

Xu, Shibo,Takamatsu, Kazutaka,Hirano, Koji,Miura, Masahiro

, p. 11797 - 11801 (2018)

A Ni(OAc)2-catalyzed C?H coupling of 8-aminoquinoline-derived benzamides with epoxides has been developed. The reaction proceeds with concomitant removal of the 8-aminoquinoline auxiliary to form the corresponding 3,4-dihydroisocoumarins directly. Additionally, the nickel catalysis is stereospecific, and the cis- and trans-epoxides are converted into the corresponding cis- and trans-dihydroisocoumarins with retention of configuration, which is complementary to previously reported palladium catalysis. Moreover, while still preliminary, the Csp3?H functionalization is also achieved in the presence of modified NiCl2 catalysts.

SYNTHESIS OF ISOCOUMARINS VIA THALLATION-OLEFINATION OF BENZOIC ACIDS

Larock, R. C.,Varaprath, S.,Lau, H. H.,Fellows, C. A.

, p. 5274 - 5284 (2007/10/02)

Benzoic acid and substituted benzoic acids are readily thallated by thallium(III) trifluoroacetate and subsequently reacted with palladium chloride and simple olefins, allylic halides, vinyl halides, or vinyl esters to give isocoumarins.The organic halide reactions are catalytic in palladium. 1,2- and 1,3-dienes also react catalytically to afford 4-alkylidene- and 3-vinyl-3,4-dihydroisocoumarins, respectively.Vinylcyclopropanes also afford 3-vinyl-3,4-dihydroisocoumarins.This highly convenient thallation-olefination approach appears quite general for the synthesis of isocoumarins.

Synthesis of Aromatic Esters, Lactones, Anhydrides, and Heterocycles via Thallation-Carbonylation of Arenes

Larock, Richard C.,Fellows, Constance A.

, p. 363 - 365 (2007/10/02)

The thallation and subsequent palladium-catalyzed carbonylation of simple arenes, benzylic and β-phenethyl alcohols, benzoic and phenylacetic acids, benzamide, and acetanilide afford benzoate esters, phthalides, 3,4-dihydroisocoumarins, phthalic and homophthalic anhydrides, phthalimide, and acetylanthranil, respectively.The carbonylation reaction proceeds in excellent yield at room temperature and atmospheric pressure and is highly stereo- and regioselective.
