340270-78-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 340270-78-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,4,0,2,7 and 0 respectively; the second part has 2 digits, 7 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 340270-78:
(8*3)+(7*4)+(6*0)+(5*2)+(4*7)+(3*0)+(2*7)+(1*8)=112
112 % 10 = 2
So 340270-78-2 is a valid CAS Registry Number.

Total synthesis of trunkamide A, a novel thiazoline-based prenylated cyclopeptide metabolite from Lissoclinum sp.

McKeever, Benedict,Pattenden, Gerald

, p. 2713 - 2727 (2007/10/03)

Full details of a total synthesis of the doubly prenylated cyclic peptide trunkamide A of marine origin, and also its C45 epimer, are described.

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.
