The CAS Registry Mumber 457058-63-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,5,7,0,5 and 8 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 457058-63:
(8*4)+(7*5)+(6*7)+(5*0)+(4*5)+(3*8)+(2*6)+(1*3)=168
168 % 10 = 8
So 457058-63-8 is a valid CAS Registry Number.

Formation of 1,3-thiazol-5(4H)-imines and 1,3-oxazol-5(4H)-imines in Aib-containing thiopeptides

Breitenmoser, Roland A.,Linden, Anthony,Heimgartner, Heinz

, p. 990 - 1018 (2007/10/03)

When tripeptides of type Axxt-Aib-Axx-OH were coupled with amino acid methyl esters by means of commonly used coupling reagents, the formation of 1,3-thiazol-5(4H)-imines and 1,3-oxazol-5(4H)-imines was observed. With the aim of understanding w
