Check Digit Verification of cas no

The CAS Registry Mumber 19934-71-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,9,9,3 and 4 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 19934-71:
(7*1)+(6*9)+(5*9)+(4*3)+(3*4)+(2*7)+(1*1)=145
145 % 10 = 5
So 19934-71-5 is a valid CAS Registry Number.

An Efficient Stereoselective Total Synthesis of All Stereoisomers of the Antibiotic Thiamphenicol through Ruthenium-Catalyzed Asymmetric Reduction by Dynamic Kinetic Resolution

Perez, Marc,Echeverria, Pierre-Georges,Martinez-Arripe, Elsa,Ez Zoubir, Mehdi,Touati, Ridha,Zhang, Zhaoguo,Genet, Jean-Pierre,Phansavath, Phannarath,Ayad, Tahar,Ratovelomanana-Vidal, Virginie

, p. 5949 - 5958 (2015/09/22)

Thiamphenicol is a widely used antibiotic that exhibits activity against numerous Gram-positive and Gram-negative pathogens. Here, we describe the expedient synthesis of its four stereoisomers through a dynamic kinetic resolution that follows a ruthenium-catalyzed asymmetric hydrogenation or a hydrogen transfer reaction as the key step.
