109321-51-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 109321-51-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,9,3,2 and 1 respectively; the second part has 2 digits, 5 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 109321-51:
(8*1)+(7*0)+(6*9)+(5*3)+(4*2)+(3*1)+(2*5)+(1*1)=99
99 % 10 = 9
So 109321-51-9 is a valid CAS Registry Number.

Study of triaryl-based sulfamic acid derivatives as HPTPβ inhibitors
Huang, Guozhi,Li, Song,Wei, Zhao,Xie, Fei,Zhang, Wenjuan,Zheng, Zhibing
, (2020)
A series of novel triaryl-based sulfamic acid analogs was designed, synthesized and evaluated as inhibitors of human protein tyrosine phosphatase beta (HPTPβ). A novel, easy and efficient synthetic method was developed for target compounds, and the activi
