Check Digit Verification of cas no

The CAS Registry Mumber 1044743-40-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,4,4,7,4 and 3 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1044743-40:
(9*1)+(8*0)+(7*4)+(6*4)+(5*7)+(4*4)+(3*3)+(2*4)+(1*0)=129
129 % 10 = 9
So 1044743-40-9 is a valid CAS Registry Number.

Synthesis, cytotoxicity, and antioxidative activity of minor prenylated chalcones from Humulus lupulus

Vogel, Susanne,Heilmann, Joerg

experimental part, p. 1237 - 1241 (2009/07/04)

The minor hop (Humulus lupulus) chalcones 3′-geranylchalconaringenin (3), 5′-prenylxanthohuraol (4), flavokawin (5), xanthohumol H (8), xanthohumol C (9), and 1″,2″-dihydroxanthohumol C (10) were synthesized. The non-natural chalcones 3′-geranyl-6′-O- methylchalconaringenin (2), 3′-methylflavokawin (6), and 2′-0-methyl-3′-prenylchalconaringenin (7) were also synthesized. Cytotoxicity was investigated in HeLa cells, and these compounds all had IC 50 values comparable to xanthohumol (8.2-19.2 μM). The ORAC-fluorescein assay revealed potent antioxidative activity for 7 and 8 with 5.2 and 4.8 Trolox equivalents, respectively.
