Check Digit Verification of cas no
The CAS Registry Mumber 57609-63-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,7,6,0 and 9 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 57609-63:
(7*5)+(6*7)+(5*6)+(4*0)+(3*9)+(2*6)+(1*3)=149
149 % 10 = 9
So 57609-63-9 is a valid CAS Registry Number.

Organocatalytic Double Ugi Reaction with Statistical Amplification of Product Enantiopurity: A Linker Cleavage Approach to Access Highly Enantiopure Ugi Products

Here we report an organocatalytic double Ugi reaction combining the enantioselective process and ee enhancement in a single operation to afford the chiral Ugi products with very high ee values. Both bisisocyanides and bisanilines tethered by carbonate and diester, respectively, were designed to accomplish this double multicomponent reaction that formed 10 new chemical bonds (4 C-N, 2 C-C, 2 C-O, and 2 N-H bonds). The strategy was further applied for the fast construction of an enantiomerically enriched macrocycle.
