100422-04-6 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 100422-04-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,0,4,2 and 2 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 100422-04:
(8*1)+(7*0)+(6*0)+(5*4)+(4*2)+(3*2)+(2*0)+(1*4)=46
46 % 10 = 6
So 100422-04-6 is a valid CAS Registry Number.

Syntheses and lipophilicity measurement of Nα/N-terminus-1,1-dihydroperfluoroalkylated α-amino acids and small peptides

DesMarteau, Darryl D.,Lu, Changqing

, p. 1326 - 1334 (2008/02/08)

(1,1-Dihydroperfluoroalkyl)phenyliodonium N,N-bis(trifluoromethylsulfonyl)imides (4, n = 0-2) were synthesized and used to transfer the corresponding 1,1-dihydroperfluoroalkyl groups to the α-amino group of (l)tyrosine. The obtained Nα-2,2,2-trifluoroethylated (l)tyrosine (6, n = 0) was further used as the N-terminus in the solid phase peptide synthesis of leucine enkephalin analogue. The lipophilicity of the Nα-1,1-dihydroperfluoroalkylated (l)tyrosines (6, n = 0-2) and N-terminus-2,2,2-trifluoroethylated leucine enkephalin analogue (7), as well as the corresponding parent compounds, was measured.
