Check Digit Verification of cas no

The CAS Registry Mumber 845510-98-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,4,5,5,1 and 0 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 845510-98:
(8*8)+(7*4)+(6*5)+(5*5)+(4*1)+(3*0)+(2*9)+(1*8)=177
177 % 10 = 7
So 845510-98-7 is a valid CAS Registry Number.

Cyclic peptides containing a δ-sugar amino acid - Synthesis and evaluation as artificial receptors

Billing, Johan F.,Nilsson, Ulf J.

, p. 863 - 874 (2007/10/03)

An Fmoc-protected δ-sugar amino acid, prepared by oxidation of a glucosamine derivative, was coupled to three different tripeptide tert-butyl esters (H-Tyr-Tyr-Tyr-OtBu, H-Tyr-Glu(OBzl)-Tyr-OtBu and H-Tyr-Arg(Mtr)-Tyr-OtBu) and the resulting sugar amino acid/amino acid hybrids were transformed into dimers that were subsequently cyclized to give three C2-symmetric macrocycles. The macrocycles were deprotected and their binding properties towards p-nitrophenyl glycosides, nucleotides, and purines were examined. Of the ligands screened, only some of the purines showed weak, but significant, binding.
