Check Digit Verification of cas no

The CAS Registry Mumber 19490-53-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,9,4,9 and 0 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 19490-53:
(7*1)+(6*9)+(5*4)+(4*9)+(3*0)+(2*5)+(1*3)=130
130 % 10 = 0
So 19490-53-0 is a valid CAS Registry Number.

Highly regioselective Pd-catalyzed intermolecular aminoacetoxylation of alkenes and evidence for cis-aminopalladation and SN2 C-O bond formation

Liu, Guosheng,Stahl, Shannon S.

, p. 7179 - 7181 (2006)

Synthetic methods that achieve oxidative 1,2-difunctionalization of alkenes are very powerful in organic chemistry. Here we report the first examples of intermolecular Pd-catalyzed aminoacetoxylation of alkenes with phthalimide as the nitrogen source and PhI(OAc)2 as the stoichiometric oxidant and source of acetate. These reactions are highly regio- and diastereoselective, and mechanistic studies reveal that the reaction proceeds via cis-aminopalladation of the alkene followed by oxidative cleavage of the intermediate Pd-C bond with inversion of stereochemistry.
