943621-73-6 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 943621-73-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,4,3,6,2 and 1 respectively; the second part has 2 digits, 7 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 943621-73:
(8*9)+(7*4)+(6*3)+(5*6)+(4*2)+(3*1)+(2*7)+(1*3)=176
176 % 10 = 6
So 943621-73-6 is a valid CAS Registry Number.

Green Organocatalytic Dihydroxylation of Alkenes

Theodorou, Alexis,Triandafillidi, Ierasia,Kokotos, Christoforos G.

, p. 1502 - 1509 (2017/04/01)

An inexpensive, green, metal-free one-pot procedure for the dihydroxylation of alkenes is described. H2O2 and 2,2,2-trifluoroacetophenone were employed as the oxidant and organocatalyst, respectively, in this highly sustainable protocol in which a variety of homoallylic alcohols, aminoalkenes, and simple alkenes were converted into the corresponding polyalcohols in good to excellent yields. This process takes advantage of an epoxidation reaction followed by an acidic treatment in which water participates in the ring opening of the in situ prepared epoxide to lead to the desired product.

Gold-catalyzed cycloisomerizations of ene-ynamides

Couty, Sylvain,Meyer, Christophe,Cossy, Janine

experimental part, p. 1809 - 1832 (2009/06/28)

The gold-catalyzed cycloisomerizations of 1,6-ene-ynamides proceed under mild conditions and lead to cyclobutanones from terminal or trimethylsilyl substituted ynamides, or to carbonyl compounds bearing a 2,3-methanopyrrolidine subunit from substrates pos
