Check Digit Verification of cas no
The CAS Registry Mumber 26922-99-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,6,9,2 and 2 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 26922-99:
(7*2)+(6*6)+(5*9)+(4*2)+(3*2)+(2*9)+(1*9)=136
136 % 10 = 6
So 26922-99-6 is a valid CAS Registry Number.

Paeonianins A-E, new dimeric and monomeric ellagitannins from the fruits of Paeonia lactiflora
Tanaka, Takashi,Fukumori, Masatake,Ochi, Tomoko,Kouno, Isao
, p. 759 - 763 (2007/10/03)
Four new dimeric ellagitannins, paeonianins A-D (2-5), were isolated from the fruits of Paeonia lactiflora, together with a new ellagitannin monomer, paeonianin E (1). Their structures were determined by spectroscopic methods. Paeonianins A-D (2-5) are positional isomers formed by condensation of pentagalloyl-β-D-glucose (8) with 5-desgalloylstachyurin (6) or casuariin (7). Paeonianin E is a C-glycosidic ellagitannin having a gallic acid methyl ester moiety at the glucose C-1 position. This is the first report of the isolation of dimeric ellagitannins from a plant in the family Paeoniaceae.
