183793-57-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 183793-57-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,3,7,9 and 3 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 183793-57:
(8*1)+(7*8)+(6*3)+(5*7)+(4*9)+(3*3)+(2*5)+(1*7)=179
179 % 10 = 9
So 183793-57-9 is a valid CAS Registry Number.

Synthesis of an enantiomerically pure serine-derived thiazole
Sowinski, Jennifer A.,Toogood, Peter L.
, p. 7671 - 7676 (2007/10/03)
Previously reported methods for preparing enantiomerically pure thiazoles are inadequate for the synthesis of inherently labile O-alkyl serine-derived thiazoles. The intermediate N-Boc-(O-methylseryl) thiazolines are very susceptible to tautomerization, e
