Check Digit Verification of cas no

The CAS Registry Mumber 189691-23-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,9,6,9 and 1 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 189691-23:
(8*1)+(7*8)+(6*9)+(5*6)+(4*9)+(3*1)+(2*2)+(1*3)=194
194 % 10 = 4
So 189691-23-4 is a valid CAS Registry Number.

Structure-activity relationships of bergenin derivatives effect on α-glucosidase inhibition

Kashima, Yusei,Yamaki, Hidehiko,Suzuki, Takuya,Miyazawa, Mitsuo

, p. 1162 - 1170 (2013/12/04)

The α-glucosidase inhibitory activities of bergenin derivatives were evaluated. Bergenin derivatives were synthesized from bergenin which is a characteristic compound of B. ligulata. A new bergenin derivative, 11-O-(3',4'-dimethoxybenzoyl)-bergenin showed

Synthesis and biological evaluation of bergenin analogues as mushroom tyrosinase inhibitors

Kashima, Yusei,Miyazawa, Mitsuo

, p. 1533 - 1541 (2013/03/13)

In this manuscript, we synthesized a series of bergenin analogues, analyzed their structural importance for two biologic activities (anitioxidant activity (ORAC) and mushroom tyrosinase inhibitory activity). Among them, compound 5 which contains catechol moiety exhibited the most antioxidant activity (3.75 μmol of Trolox equiv. per μmol of 5). Furthermore, compound 5 was found to be the most potent (IC50 value = 17.5 ± 0.04 μM) when compared with the standard tyrosinase inhibitors of arbutin (IC50 value = 221.8 ± 1.9 μM) and kojic acid (IC50 value = 46.6 ± 3.8 μM). The bergenin moiety, the ester linkage, and benzoic acid moiety of bergenin derivatives affected two biologic activities. Tyrosinase inhibitory activity was affected by substituents of benzoic acid moiety. This manuscript provides a good foundation for the design and development of new tyrosinase inhibitors.
