Check Digit Verification of cas no

The CAS Registry Mumber 644989-77-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,4,4,9,8 and 9 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 644989-77:
(8*6)+(7*4)+(6*4)+(5*9)+(4*8)+(3*9)+(2*7)+(1*7)=225
225 % 10 = 5
So 644989-77-5 is a valid CAS Registry Number.

Frontiers and opportunities in chemoenzymatic synthesis

Mortison, Jonathan D.,Sherman, David H.

scheme or table, p. 7041 - 7051 (2010/12/20)

Natural product biosynthetic pathways have evolved enzymes with myriad activities that represent an expansive array of chemical transformations for constructing secondary metabolites. Recently, harnessing the biosynthetic potential of these enzymes through chemoenzymatic synthesis has provided a powerful tool that often rivals the most sophisticated methodologies in modern synthetic chemistry and provides new opportunities for accessing chemical diversity. Herein, we describe our research efforts with enzymes from a broad collection of biosynthetic systems, highlighting recent progress in this exciting field.

Synthesis of Cryptophycins via an N-Acyl-β-lactam Macrolactonization

Vidya, Ramdas,Eggen, MariJean,Nair, Sajiv K.,Georg, Gunda I.,Himes, Richard H.

, p. 9687 - 9693 (2007/10/03)

An efficient and concise approach to the synthesis of the macrolide core of the cryptophycins has been developed. A novel macrolactonization utilizing a reactive acyl-β-lactam intermediate incorporates the β-amino acid moiety within the 16-membered macrol
