Check Digit Verification of cas no

The CAS Registry Mumber 1417890-26-6 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,1,7,8,9 and 0 respectively; the second part has 2 digits, 2 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1417890-26:
(9*1)+(8*4)+(7*1)+(6*7)+(5*8)+(4*9)+(3*0)+(2*2)+(1*6)=176
176 % 10 = 6
So 1417890-26-6 is a valid CAS Registry Number.

Model studies on the first enzyme-catalyzed Ugi reaction

K?ossowski, Szymon,Wiraszka, Barbara,Ber?ozecki, Stanis?aw,Ostaszewski, Ryszard

, p. 566 - 569 (2013)

Multicomponent reactions are powerful tools for organic chemistry, and among them, the Ugi reaction provides remarkable improvement in many fields of organic chemistry such us combinatorial chemistry, medicinal chemistry, and peptide chemistry. A new, enzyme-catalyzed example of the Ugi three-component reaction is presented. The studies include the selection of an enzyme as well as determination of the scope and limitations of the newly described reaction. The presented method combines the enzyme promiscuity and multicomponent reaction advantages in the first one-pot formation of dipeptide 1.
