Check Digit Verification of cas no

The CAS Registry Mumber 155997-93-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,5,9,9 and 7 respectively; the second part has 2 digits, 9 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 155997-93:
(8*1)+(7*5)+(6*5)+(5*9)+(4*9)+(3*7)+(2*9)+(1*3)=196
196 % 10 = 6
So 155997-93-6 is a valid CAS Registry Number.

Synthesis and digestibility inhibition of diarylheptanoids: Structure- activity relationship

Bratt, Katharina,Sunnerheim, Kerstin

, p. 2703 - 2713 (1999)

(±)-5-Hydroxy-1,7-bis-(4'-hydroxyphenyl)-3-heptanone (2a), (±)5- hydroxyl-1-(4'-hydroxyphenyl)-7-phenyl-3-heptanone (2b), (±)-5-hydroxy-7- (4'-hydroxyphenyl)-1-phenyl-3-heptanone (2c), and (±)-5-hydroxy-1,7- bis(phenyl)-3-heptanone (2d) have been synthesized to study the structure- activity relationship regarding digestibility inhibition in vitro in cow rumen fluid. The activities were compared with the activity of chiral (S)-2a and its glucoside platyphylloside (1), isolated from Betula pendula. Compound 2a was slightly less active, 2b and 2c were more active, and 2d was less active than (S)-2a and platyphylloside.
