Description
Tuliposide is a prohapten contained in tulip bulbs and
in alstroemerias (Tulipa spp.; Alstroemeria spp.; Lilium
spp.). It is rapidly hydrolyzed to Tulipalin A and
represents a common occupational problem among
workers in the European tulip industry.
Check Digit Verification of cas no
The CAS Registry Mumber 19870-30-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,9,8,7 and 0 respectively; the second part has 2 digits, 3 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 19870-30:
(7*1)+(6*9)+(5*8)+(4*7)+(3*0)+(2*3)+(1*0)=135
135 % 10 = 5
So 19870-30-5 is a valid CAS Registry Number.

A NEW SYNTHETIC METHOD FOR 1-O-ACYL-β-D-GLUCOPYRANOSES USING TRI-O-TRIFLUOROACETYL-1,6-ANHYDROGLUCOSE. SYNTHESIS OF TULIPOSIDE-A.

Tri-O-trifluoroacetyl-1,6-anhydroglucose 1 was proved to be an useful precursor of 1β-O-acylglucoses.Treatment of 1 with TiBr4 in boiling CF3COOH afforded 2,3,4,6-tetra-O-trifluoroacetyl-α-D-glucopyranosyl bromide,which on reaction with a silver carboxylate in benzene gave the 1β-O-acyl derivative.The TFA group was removed either by contact the compound with methanol or by alumina chromatography yielding 1β-O-acyl-D-glucopyranose.By this method tuliposide-A, 1-O-(γ-hydroxy-α-methylenebutyroyl)-β-D-glucopyranose, was synthesized.
