Check Digit Verification of cas no
The CAS Registry Mumber 138346-55-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,8,3,4 and 6 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 138346-55:
(8*1)+(7*3)+(6*8)+(5*3)+(4*4)+(3*6)+(2*5)+(1*5)=141
141 % 10 = 1
So 138346-55-1 is a valid CAS Registry Number.

Stereocontrolled Total Synthesis of Galactostasin from Serine
Dondoni, Alessandro,Merino, Pedro,Perrone, Daniela
, p. 1576 - 1578 (2007/10/02)
An efficient stereoselective total synthesis of (-)-galactostasin (-)-1 from N-tert-butoxycarbonyl-2,3-isopropylidene L-serine methyl ester (21percent overall yield) is described via thiazole intermediates serving as protected aldehydes; the parallel synt
