118609-93-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 118609-93-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,8,6,0 and 9 respectively; the second part has 2 digits, 9 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 118609-93:
(8*1)+(7*1)+(6*8)+(5*6)+(4*0)+(3*9)+(2*9)+(1*3)=141
141 % 10 = 1
So 118609-93-1 is a valid CAS Registry Number.

The title peptide N-benzyloxycarbonyl-ΔLeu-L-Ala-L-Leu-OCH3 [methyl N-(benzyloxycarbonyl)-α,β-dehydroleucyl-L-alanyl-L-leucinate], C24H35N3O6, was synthesized, in the solution phase. The peptide adopt

THE SYNTHESES OF N-FREE α-DEHYDROAMINO ACID ESTERS AND N-ACETYL DEHYDRODIPEPTIDE ESTER FROM N-CARBOXY α-DEHYDROAMINO ACID ANHYDRIDE

Shin, Chung-gi,Yonezawa, Yasuchika,Yoshimura, Juji

, p. 1635 - 1638 (2007/10/02)

N-Carboxy α-dehydroamino acid anhydride, derived from N-benzyloxycarbonyl α-dehydroamino acid (DHA) and thionyl chloride, was found to be very useful for the synthesis of N-free DHA ester by alcoholysis and N-acetyl dehydrodipeptide ester by coupling was
