892869-55-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 892869-55-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,9,2,8,6 and 9 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 892869-55:
(8*8)+(7*9)+(6*2)+(5*8)+(4*6)+(3*9)+(2*5)+(1*5)=245
245 % 10 = 5
So 892869-55-5 is a valid CAS Registry Number.

Pentacyclic triterpenes. Part 3: Synthesis and biological evaluation of oleanolic acid derivatives as novel inhibitors of glycogen phosphorylase
Chen, Jun,Liu, Jun,Zhang, Luyong,Wu, Guanzhong,Hua, Weiyi,Wu, Xiaoming,Sun, Hongbin
, p. 2915 - 2919 (2007/10/03)
Oleanolic acid and its synthetic derivatives have been identified as novel inhibitors of glycogen phosphorylase. Within this series of compounds, 4 (IC50 = 3.3 μM) is the most potent GPa inhibitor. Preliminary structure-activity relationships of the oleanolic acid derivatives are discussed.
