Check Digit Verification of cas no

The CAS Registry Mumber 1421689-05-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,2,1,6,8 and 9 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1421689-05:
(9*1)+(8*4)+(7*2)+(6*1)+(5*6)+(4*8)+(3*9)+(2*0)+(1*5)=155
155 % 10 = 5
So 1421689-05-5 is a valid CAS Registry Number.

Discovering Novel α-aminoacyl-Containing Proline Derivatives with Potent and Selective Inhibitory Activity Against Dipeptidyl Peptidase IV: Design, Synthesis, Biological Evaluation, and Molecular Modeling

Zhang, Xiaodong,Wang, Jiang,Li, Zeng,Liu, Hong,Su, Mingbo,Li, Jingya,Li, Jia

, p. 843 - 852,10 (2012/12/12)

On the basis of the enzyme-binding features of known potent inhibitors of dipeptidyl peptidase IV, novel α-aminoacyl-containing proline analogs (8Aa-8Ak, 8Ba-8Bj, 8Ca-8Ck, and 8Da-8Di) with the S configuration were designed, synthesized, and their activit
