Check Digit Verification of cas no

The CAS Registry Mumber 1621188-47-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,6,2,1,1,8 and 8 respectively; the second part has 2 digits, 4 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1621188-47:
(9*1)+(8*6)+(7*2)+(6*1)+(5*1)+(4*8)+(3*8)+(2*4)+(1*7)=153
153 % 10 = 3
So 1621188-47-3 is a valid CAS Registry Number.

Gold(I)-Catalyzed Direct Stereoselective Synthesis of Deoxyglycosides from Glycals

Palo-Nieto, Carlos,Sau, Abhijit,Galan, M. Carmen

, p. 14041 - 14044 (2017)

Au(I) in combination with AgOTf enables the unprecedented direct and α-stereoselective catalytic synthesis of deoxyglycosides from glycals. Mechanistic investigations suggest that the reaction proceeds via Au(I)-catalyzed hydrofunctionalization of the enol ether glycoside. The room temperature reaction is high yielding and amenable to a wide range of glycal donors and OH nucleophiles.

Palladium-Catalyzed Direct Stereoselective Synthesis of Deoxyglycosides from Glycals

Sau, Abhijit,Williams, Ryan,Palo-Nieto, Carlos,Franconetti, Antonio,Medina, Sandra,Galan, M. Carmen

supporting information, p. 3640 - 3644 (2017/03/21)

Palladium(II) in combination with a monodentate phosphine ligand enables the unprecedented direct and α-stereoselective catalytic synthesis of deoxyglycosides from glycals. Initial mechanistic studies suggest that in the presence of N-phenyl-2-(di-tert-butylphosphino)pyrrole as the ligand, the reaction proceeds via an alkoxy palladium intermediate that increases the proton acidity and oxygen nucleophilicity of the alcohol. The method is demonstrated with a wide range of glycal donors and acceptors, including substrates bearing alkene functionalities.
