126594-58-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 126594-58-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,6,5,9 and 4 respectively; the second part has 2 digits, 5 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 126594-58:
(8*1)+(7*2)+(6*6)+(5*5)+(4*9)+(3*4)+(2*5)+(1*8)=149
149 % 10 = 9
So 126594-58-9 is a valid CAS Registry Number.

Biosynthesis of the dimeric ellagitannin, cornusiin E, in Tellima grandiflora

Niemetz, Ruth,Schilling, Gerhard,Gross, Georg G.

, p. 109 - 114 (2003)

First evidence for the in vitro synthesis of a dimeric ellagitannin has been obtained with cell-free extracts from the weed Tellima gratidiflora (fringe cups, Saxifragaceae). Partially purified enzyme preparations from leaves of this plant catalyzed the oxidation of 1,2,3,4,6-pentagalloyl-β -D-glucose to the monomeric ellagitannin, tellimagrandin II, followed by oxidative coupling of two units of this intermediate to yield a dimeric derivative. Chemical degradation, MALDI-TOF mass spectrometry, 1H and 13C nuclear magnetic resonance, and CD spectroscopy were employed to identify this enzyme reaction product as cornusiin E which is characterized by a (S)-valoneoyl bridge between glucose-positions 2, 4′ and 6′. This result was supported by comparison with data obtained for cornusiin E that had been isolated from leaves of intact T. grandiflora plants. No indication for the earlier proposed existence of rugosin D (an isomer with a 1,4′6′-bound valoneoyl unit) in T. grandiflora has been obtained in this investigation.
