Check Digit Verification of cas no

The CAS Registry Mumber 550309-53-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,5,0,3,0 and 9 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 550309-53:
(8*5)+(7*5)+(6*0)+(5*3)+(4*0)+(3*9)+(2*5)+(1*3)=130
130 % 10 = 0
So 550309-53-0 is a valid CAS Registry Number.

Column chromatography-free solution-phase synthesis of a natural piper-amide-like compound library

We have achieved an efficient solution-phase parallel synthesis of a library of natural piper-amide-like compounds from the bifunctional β-phosphono-N-hydroxy-succinimidyl ester intermediate. The primary important feature in our study is the construction of natural-product-like molecules through the adaptation of sophisticated organic reactions that create water-soluble byproducts for a chromatography-free purification. This simple and efficient method rapidly provides a combinatorial library of high yield and purity. The library was evaluated against GPCR targets to demonstrate its potential use as a tool for drug discovery and in chemical biology.
