173913-76-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 173913-76-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,3,9,1 and 3 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 173913-76:
(8*1)+(7*7)+(6*3)+(5*9)+(4*1)+(3*3)+(2*7)+(1*6)=153
153 % 10 = 3
So 173913-76-3 is a valid CAS Registry Number.

Synthesis of l-azatyrosine using pseudoephedrine as a chiral auxiliary
-
, (2008/06/13)
A practical synthesis of the potential chemotherapeutic agent L-azatyrosine is described. The key step involved the alkylation of (R,R)-(-)-pseudoephedrine glycinamide with 5-benzenesulfonyloxy-2-iodomethylpyridine and proceeded in 70-95% yield and 89-95%
