Check Digit Verification of cas no

The CAS Registry Mumber 548756-56-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,4,8,7,5 and 6 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 548756-56:
(8*5)+(7*4)+(6*8)+(5*7)+(4*5)+(3*6)+(2*5)+(1*6)=205
205 % 10 = 5
So 548756-56-5 is a valid CAS Registry Number.

Activated Self-Resolution and Error-Correction in Catalytic Reaction Networks**

Schaufelberger, Fredrik,Ramstr?m, Olof

, p. 10335 - 10340 (2021/05/07)

Understanding the emergence of function in complex reaction networks is a primary goal of systems chemistry and origin-of-life studies. Especially challenging is to create systems that simultaneously exhibit several emergent functions that can be independently tuned. In this work, a multifunctional complex reaction network of nucleophilic small molecule catalysts for the Morita-Baylis-Hillman (MBH) reaction is demonstrated. The dynamic system exhibited triggered self-resolution, preferentially amplifying a specific catalyst/product set out of a many potential alternatives. By utilizing selective reversibility of the products of the reaction set, systemic thermodynamically driven error-correction could also be introduced. To achieve this, a dynamic covalent MBH reaction based on adducts with internal H-transfer capabilities was developed. By careful tuning of the substituents, rate accelerations of retro-MBH reactions of up to four orders of magnitude could be obtained. This study thus demonstrates how efficient self-sorting of catalytic systems can be achieved through an interplay of several complex emergent functionalities.
