Check Digit Verification of cas no

The CAS Registry Mumber 194281-34-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,4,2,8 and 1 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 194281-34:
(8*1)+(7*9)+(6*4)+(5*2)+(4*8)+(3*1)+(2*3)+(1*4)=150
150 % 10 = 0
So 194281-34-0 is a valid CAS Registry Number.

Bibenzyl derivatives from Pellia epiphylla

Cullmann, Frank,Becker, Hans,Pandolfi, Enrique,Roeckner, Eckard,Eicher, Theophil

, p. 1235 - 1247 (2007/10/03)

Reinvestigation of the phenolic constituents from a diethyl ether extract of gametophytes of Pellia epiphylla yielded pellepiphyllin, 7- hydroxypellepiphyllin, perrottetin E, perrottetin E-11-methyl ether, 14'- hydroxyperrottetin E, 10'-hydroxyperrottetin E, 10'-hydroxyperrottetin E-11- methyl ether, 10,10'-dihydroxyperrottetin E and 13',13'''-bis(10'- hydroxyperrottetin E). The structures of three bisbibenzyls published earlier are revised. The new structures have been elucidated by two-dimensional NMR- techniques and chemical synthesis. In contrast to previous publications, pellepiphyllin has been found as a constituent of P. epiphylla.
