103633-31-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 103633-31-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,3,6,3 and 3 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 103633-31:
(8*1)+(7*0)+(6*3)+(5*6)+(4*3)+(3*3)+(2*3)+(1*1)=84
84 % 10 = 4
So 103633-31-4 is a valid CAS Registry Number.

SYNTHESIS OF UVARETIN, AN ANTITUMOUR AND ANTIMICROBIAL FLAVONOID

Malterud, Karl Egil,Undheim, Jorunn,Erdal, John Erik

, p. 4807 - 4810 (2007/10/02)

The flavonoid uvaretin (1-(2,4-dihydroxy-6-methoxy-3-((2-hydroxyphenyl)-methyl)-phenyl)-3-phenyl-1-propanone), known to be active against some tumours and several bacteria, has been synthesized in six steps from 2',4',6'-trimethoxyacetophenone, 2-hydroxybenzaldehyde and benzaldehyde.

Aromatic Benzylation: Part III - Synthesis of Uvaretin, Isouvaretin and Related Nuclear Benzylated Dihydrochalcones

Jain, Amolak C.,Arya, Prabhat

, p. 1015 - 1022 (2007/10/02)

Reaction of 2-O-methylphloroacetophenone (5) with either o-benzyloxybenzyl alcohol (3) in the presence of boron trifluoride etherate and dioxan or with o-benzyloxybenzyl bromide (4) in the presence of methanolic potash affords 5-C-(o-benzyloxybenzyl) derivative (6) and its 3-C-isomer (7).Their orientation has been arrived at from a general behaviour of the chemical shift of chelated hydroxyl group in C-benzylated o-hydroxyacetophenones when C-benzyl group is present ortho or para to the chelated hydroxyl.Partial benzyl ether (9) of 6 and the complete benzyl ether (12) of 7 undergo facile condensation with benzaldehyde in the presence of alkali to give 10 and 13 respectively.These chalcones on hydrogenation in the presence of 10percent Pd-C afford uvaretin (11) and isouvaretin (14) respectively possessing physical characteristics identical with those of the natural samples.A parallel series of reactions starting from resacetophenone (15) provides C-benzylated dihydrochalcones 22 and 25 as analogues of uvaretin and isouvaretin respectively.
