Check Digit Verification of cas no
The CAS Registry Mumber 50276-98-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,0,2,7 and 6 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 50276-98:
(7*5)+(6*0)+(5*2)+(4*7)+(3*6)+(2*9)+(1*8)=117
117 % 10 = 7
So 50276-98-7 is a valid CAS Registry Number.

Structure elucidation of metabolites of swertiamarin produced by Aspergillus niger
Jun, Chang,Xue-Ming, Zhao,Chang-Xiao, Liu,Tie-Jun, Zhang
, p. 22 - 25 (2008)
The in vitro metabolism of swertiamarin was carried out in preparative scale using the fungus Aspergillus niger and the metabolites were isolated by semi-preparative HPLC combined with liquid-liquid extraction. Two metabolites, erythrocentaurin and one new compound were obtained and identified by 1H, 13C and 2D NMR and high resolution MS. The anti-inflammatory activity of the novel metabolite was tested and compared with that of swertiamarin in a mice model.
