Check Digit Verification of cas no

The CAS Registry Mumber 123040-75-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,3,0,4 and 0 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 123040-75:
(8*1)+(7*2)+(6*3)+(5*0)+(4*4)+(3*0)+(2*7)+(1*5)=75
75 % 10 = 5
So 123040-75-5 is a valid CAS Registry Number.

Optimization of triazoles as novel and potent nonphlorizin SGLT2 inhibitors

Du, Xiaohui,Lizarzaburu, Mike,Turcotte, Simon,Lee, Taeweon,Greenberg, Joanne,Shan, Bei,Fan, Peter,Ling, Yun,Medina, Julio C.,Houze, Jonathan

scheme or table, p. 3774 - 3779 (2011/08/06)

Previous efforts have led to the identification of a potent, selective, and nonphlorizin based SGLT2 inhibitor 1. This Letter describes efforts to further optimize the potency, microsomal stability, solubility and pharmacokinetic properties of this series of SGLT2 inhibitors. From these efforts, compounds 28 and 32 have improved solubility and pharmacokinetic properties compared to compound 1.
