Check Digit Verification of cas no

The CAS Registry Mumber 28034-80-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,8,0,3 and 4 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 28034-80:
(7*2)+(6*8)+(5*0)+(4*3)+(3*4)+(2*8)+(1*0)=102
102 % 10 = 2
So 28034-80-2 is a valid CAS Registry Number.

Synthesis and anti-hyperglycemic activity of hesperidin derivatives

Zhang, Baoshun,Chen, Tingting,Chen, Zhu,Wang, Mingxue,Zheng, Dengyu,Wu, Jinfeng,Jiang, Xiaofei,Li, Xuegang

, p. 7194 - 7197 (2012)

A series of hesperidin derivatives were prepared and identified by IR, 1H NMR, and MS spectra. These compounds were evaluated in vitro and in vivo based on α-glucosidase inhibition, glucose consumption of HepG2 cells, and blood glucose level in streptozotocin-induced diabetic mice. The results revealed that all the compounds exhibited anti-hyperglycemic activities. The inhibition at 10-3 M of compounds 3 and 7a on α-glucosidase were 55.02% and 53.34%, respectively, as compared to 54.80% by acarbose. Treated by compound 3 and the reference drug metformin, glucose consumption of HepG2 cell were 1.78 and 2.11 mM, respectively. After the streptozotocin-induced diabetic mice were oral administrated with compound 3 at 100 mg kg-1 d-1 for 10 days, the blood glucose level of 3 treated mice (13.23 mM, P 0.05) showed significant difference when compared to model control (23.03 mM). Thus, compound 3 exhibited promising anti-hyperglycemic activity.
