Check Digit Verification of cas no

The CAS Registry Mumber 101890-49-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,1,8,9 and 0 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 101890-49:
(8*1)+(7*0)+(6*1)+(5*8)+(4*9)+(3*0)+(2*4)+(1*9)=107
107 % 10 = 7
So 101890-49-7 is a valid CAS Registry Number.

Synthesis, biological evaluation of 9-N-substituted berberine derivatives as multi-functional agents of antioxidant, inhibitors of acetylcholinesterase, butyrylcholinesterase and amyloid-β aggregation

Shan, Wen-Jun,Huang, Ling,Zhou, Qi,Meng, Fan-Chao,Li, Xing-Shu

experimental part, p. 5885 - 5893 (2012/01/04)

A series of 9-N-substituted berberine derivatives were synthesized and biologically evaluated as antioxidant and inhibitors of acetylcholinesterase (AChE), butyrylcholinesterase and amyloid-β aggregation. Most of these compounds exhibited very good antioxidant activities, inhibitive activities of AChE and amyloid-β aggregation. Among them, compound 8d, (o-methylphenethyl)amino linked at the 9-position of berberine, was found to be a good antioxidant (with 4.05 μM of Trolox equivalents), potent inhibitor of AChE (an IC50 value of 0.027 μM), and high active inhibitor of amyloid-β aggregation (an IC50 value of 2.73 μM).
