24398-21-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 24398-21-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,4,3,9 and 8 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 24398-21:
(7*2)+(6*4)+(5*3)+(4*9)+(3*8)+(2*2)+(1*1)=118
118 % 10 = 8
So 24398-21-8 is a valid CAS Registry Number.

Copper-catalyzed synthesis of sulfenamides utilizing diaryl disulfides with alkyl amines

Taniguchi, Nobukazu

, p. 1917 - 1920 (2008/03/13)

The copper-catalyzed coupling of diaryl disulfides with alkyl amines can afford various sulfenamides in good yields. Furthermore, the present reaction is efficient and can be used for both of the aryl sulfide groups on disulfide. Georg Thieme Verlag Stutt

N-hydroxypyridine-2(1H)-thione derivatives of carboxylic acids as activated esters. Part II. Applications in peptide synthesis

Barton, Derek H. R.,Ferreira, J. Albert

, p. 9367 - 9386 (2007/10/03)

The N-hydroxypyridine-2(1H)-thione derivatives of two urethane-protected α-amino acids readily reacted with the α-amino acid esters or the corresponding benzenesulfenamides to give simple dipeptides in reasonable yields. The benzenesulfenamides are the re
