Check Digit Verification of cas no

The CAS Registry Mumber 90508-27-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,0,5,0 and 8 respectively; the second part has 2 digits, 2 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 90508-27:
(7*9)+(6*0)+(5*5)+(4*0)+(3*8)+(2*2)+(1*7)=123
123 % 10 = 3
So 90508-27-3 is a valid CAS Registry Number.

Solid-phase synthesis of 1,3-azole-based peptides and peptidomimetics

Biron, Eric,Chatterjee, Jayanta,Kessler, Horst

, p. 2417 - 2420 (2007/10/03)

We report highly efficient two-step procedures for the synthesis of 1,3-oxazole-, thiazole-, and imidazole-containing peptides on solid phase from dipeptides composed of C-terminal threonine, serine, cysteine, or diaminopropionic acid by using different cyclodehydration procedures followed or preceded by oxidation. The methods are compatible with Fmoc solid-phase peptide synthesis conditions and with N-Fmoc, N-Boc, N-Cbz, and N-Alloc protecting groups.
