Check Digit Verification of cas no

The CAS Registry Mumber 22490-19-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,2,4,9 and 0 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 22490-19:
(7*2)+(6*2)+(5*4)+(4*9)+(3*0)+(2*1)+(1*9)=93
93 % 10 = 3
So 22490-19-3 is a valid CAS Registry Number.

Leveraging the micellar effect: Gold-catalyzed dehydrative cyclizations in water at room temperature

Minkler, Stefan R. K.,Isley, Nicholas A.,Lippincott, Daniel J.,Krause, Norbert,Lipshutz, Bruce H.

supporting information, p. 724 - 726 (2014/03/21)

The first examples of gold-catalyzed cyclizations of diols and triols to the corresponding hetero- or spirocycles in an aqueous medium are presented. These reactions take place within nanomicelles, where the hydrophobic effect is operating, thereby driving the dehydrations, notwithstanding the surrounding water. By the addition of simple salts such as sodium chloride, reaction times and catalyst loadings can be significantly decreased.

Stereochemical control by an ester group or olefin ligand in platinum-catalyzed carboalkoxylation of 6-(1-alkoxyethoxy)-hex-2-ynoates

Nakamura, Itaru,Chan, Ching Siew,Araki, Toshiharu,Terada, Masahiro,Yamamoto, Yoshinori

experimental part, p. 1089 - 1100 (2009/12/07)

The cyclization of 6-(1-alkoxyethoxy)hex-2-ynoantes in the presence of the platinum-olefin catalyst system gave the corresponding multisubsti-tuted 2- [dihydrofuran-2(3H)-ylidene]acetates in good to high yields. The Z/E selectivity is controlled by the el
