154561-15-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 154561-15-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,4,5,6 and 1 respectively; the second part has 2 digits, 1 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 154561-15:
(8*1)+(7*5)+(6*4)+(5*5)+(4*6)+(3*1)+(2*1)+(1*5)=126
126 % 10 = 6
So 154561-15-6 is a valid CAS Registry Number.

Tannins of theaceous plants. V. Camelliatannins F, G and H, three new tannins from Camellia japonica L.
Han,Hatano,Yoshida,Okuda
, p. 1399 - 1409 (1994)
Two new complex tannins, camelliatannins F (3) and G (4), were isolated from the leaves of Camellia japonica L. (Theaceae), and their structures, each consisting of an epicatechin unit and a C-glucosidic ellagitannin moiety, were elucidated. A new dimeric hydrolyzable tannin, named camelliatannin H (5), was isolated from the fruits of this plant. Camelliins A (6) and B (7), and camelliatannin A (1) and 3 were also isolated from the fruits.
