Check Digit Verification of cas no

The CAS Registry Mumber 22077-44-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,2,0,7 and 7 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 22077-44:
(7*2)+(6*2)+(5*0)+(4*7)+(3*7)+(2*4)+(1*4)=87
87 % 10 = 7
So 22077-44-7 is a valid CAS Registry Number.

Hydrogen Bond Donor Catalyzed Cationic Polymerization of Vinyl Ethers

Kottisch, Veronika,Jermaks, Janis,Mak, Joe-Yee,Woltornist, Ryan A.,Lambert, Tristan H.,Fors, Brett P.

, p. 4535 - 4539 (2021)

The synthesis of high-molecular-weight poly(vinyl ethers) under mild conditions is a significant challenge, since cationic polymerization reactions are highly sensitive to chain-transfer and termination events. We identified a novel and highly effective h

Synthesis and cholinesterase inhibitory activity of n-phosphorylated / n-tiophosphorylated tacrine

Demkowicz, Sebastian,Dzierzbicka, Krystyna,Inkielewicz-Stepniak, Iwona,Kowalski, Szymon,Da?ko, Mateusz,Przyby?owska, Maja

, p. 947 - 957 (2020/08/19)

Background: Alzheimer’s disease (AD) is progressive and irreversible neurodegenera-tive disorder. Current pharmacotherapy is not able to stop progression of the disease and can only improve cognitive functions. Therefore, new drugs are being sought that w

A simple and efficient approach to the synthesis of 1-phosphonated 5-amino-1-H-[1,2,4]-triazole from N-functionalized imidates

Jabli, Dhiab,Dridi, Khaireddine,Efrit, Mohamed Lotfi

, p. 759 - 764 (2016/05/09)

In this study, we describe a new and easy synthetic approach to variously substituted triazoles based on the reaction of imidates with phosphorylated hydrazine in good yields. A general mechanism of the reactions was also proposed. Characterization of the products was carried out by several analytical and spectroscopic tools including infrared and nuclear magnetic resonance spectroscopies (1H,13C NMR,31P NMR).
