1322744-58-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1322744-58-0 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,2,2,7,4 and 4 respectively; the second part has 2 digits, 5 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1322744-58:
(9*1)+(8*3)+(7*2)+(6*2)+(5*7)+(4*4)+(3*4)+(2*5)+(1*8)=140
140 % 10 = 0
So 1322744-58-0 is a valid CAS Registry Number.

Convenient synthesis of chiral tryptophan derivatives using Negishi cross-coupling
Tanaka, Minoru,Hikawa, Hidemasa,Yokoyama, Yuusaku
, p. 5897 - 5901 (2011/09/19)
A facile synthetic procedure for chiral tryptophan derivatives using Negishi cross-coupling reaction of serine-derived iodoalanine with 3-haloindole is described. The best result was obtained when the reaction of N-tosyl-3-bromoindole with N-Cbz-iodoalani
