Check Digit Verification of cas no

The CAS Registry Mumber 500213-40-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,0,0,2,1 and 3 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 500213-40:
(8*5)+(7*0)+(6*0)+(5*2)+(4*1)+(3*3)+(2*4)+(1*0)=71
71 % 10 = 1
So 500213-40-1 is a valid CAS Registry Number.

Synthesis of highly substituted imidazolidine-2,4-dione (Hydantoin) through Tf2O-mediated dual activation of Boc-protected dipeptidyl compounds

Liu, Hui,Yang, Zhimin,Pan, Zhengying

supporting information, p. 5902 - 5905 (2015/01/08)

Highly substituted chiral hydantoins were readily synthesized from simple dipeptides in a single step under mild conditions. This reaction proceeded through the dual activation of an amide and a tert-butyloxycarbonyl (Boc) protecting group by Tf2O-pyridine. This method was successfully applied in the preparation of a variety of biologically active compounds, including drug analogs and natural products.

A progressive synthetic strategy for class B synergimycins

Robinson, Jennifer L.,Taylor, Rachel E.,Liotta, Lisa A.,Bolla, Megan L.,Azevedo, Enrique V.,Medina, Irene,McAlpine, Shelli R.

, p. 2147 - 2150 (2007/10/03)

Described are the syntheses of four macrocyclic peptides that are the core structure of class B synergimycins, and the synthesis of a final class B derivative. Our synthetic route to these synergimycin derivatives allows the incorporation of amino acid su

Novel antibiotics: macrocyclic peptides designed to trap Holliday junctions.

Bolla, Megan L,Azevedo, Enrique V,Smith, Jason M,Taylor, Rachel E,Ranjit, Dev K,Segall, Anca M,McAlpine, Shelli R

, p. 109 - 112 (2007/10/03)

[reaction: see text] Described are the syntheses of eight macrocyclic peptides designed to trap Holliday junctions in bacteria, thereby inhibiting bacterial growth. These macrocycles were designed from linear dimerized hexapeptides that bind to the C-2 sy
