Check Digit Verification of cas no

The CAS Registry Mumber 1421328-65-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,2,1,3,2 and 8 respectively; the second part has 2 digits, 6 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1421328-65:
(9*1)+(8*4)+(7*2)+(6*1)+(5*3)+(4*2)+(3*8)+(2*6)+(1*5)=125
125 % 10 = 5
So 1421328-65-5 is a valid CAS Registry Number.

Expedient route to functionalized and water soluble 5-6-5 imidazole-phenyl-thiazole based α-helix mimetics

Cummings, Christopher G.,Hamilton, Andrew D.

, p. 1663 - 1668 (2013/03/13)

A range of small molecule scaffolds have been shown to act as structural and functional mimics of α-helices by mimicking the i, i+4, and i+7 positions, often found at the interface of PPIs. These molecules, though potent, possess complicating features - either low water solubility, or maintenance of conformation by hydrogen-bonding networks. We have addressed these limitations by developing a scaffold with increased water solubility. Herein we present a rapid synthetic pathway to a library of 56 compounds based on a 5-6-5 scaffold, containing an imidazole-phenyl-thiazole core; the route is flexible and allows rapid installation of different substituents via high-yielding Ullman and Suzuki couplings and Hantsch thiazole syntheses.
