189459-06-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 189459-06-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,9,4,5 and 9 respectively; the second part has 2 digits, 0 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 189459-06:
(8*1)+(7*8)+(6*9)+(5*4)+(4*5)+(3*9)+(2*0)+(1*6)=191
191 % 10 = 1
So 189459-06-1 is a valid CAS Registry Number.

Synthesis of peptidyl aldehydes from thiazolidines
Galeotti, Nathalie,Plagnes, Eric,Jouin, Patrick
, p. 2459 - 2462 (2007/10/03)
Peptidyl aldehydes were synthesized using thiazolidine peptides as precursors. Hydrolysis of the heterocycles is easily accomplished using cupper salts to furnish the peptidyl aldehydes with very good yield and with no epimerization.
