868546-94-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 868546-94-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,6,8,5,4 and 6 respectively; the second part has 2 digits, 9 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 868546-94:
(8*8)+(7*6)+(6*8)+(5*5)+(4*4)+(3*6)+(2*9)+(1*4)=235
235 % 10 = 5
So 868546-94-5 is a valid CAS Registry Number.

Convergent approaches for the synthesis of the antitumoral peptide, Kahalalide F. study of orthogonal protecting groups

Gracia, Carolina,Isidro-Llobet, Albert,Cruz, Luis J.,Acosta, Gerardo A.,Alvarez, Mercedes,Cuevas, Carmen,Giralt, Ernest,Albericio, Fernando

, p. 7196 - 7204 (2006)

Kahalalide compounds are peptides that are isolated from a Hawaiian herbivorous marine species of mollusc, Elysia rufescens, and its diet, the green alga Bryopsis sp. Kahalalide F and its synthetic analogues are the most promising compounds of the Kahalalide family because they show antitumoral activity. Linear solid-phase syntheses of Kahalalide F have been reported. Here we describe several new improved synthetic routes based on convergent approaches with distinct orthogonal protection schemes for the preparation of Kahaladide analogues. These strategies allow a better control and characterization of the intermediates because more reactions are performed in solution.
