17890-12-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 17890-12-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,7,8,9 and 0 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 17890-12:
(7*1)+(6*7)+(5*8)+(4*9)+(3*0)+(2*1)+(1*2)=129
129 % 10 = 9
So 17890-12-9 is a valid CAS Registry Number.

Multifunctional Building Blocks Compatible with Photoredox-Mediated Alkylation for DNA-Encoded Library Synthesis

Badir, Shorouk O.,Sim, Jaehoon,Billings, Katelyn,Csakai, Adam,Zhang, Xuange,Dong, Weizhe,Molander, Gary A.

, p. 1046 - 1051 (2020)

DNA-encoded library (DEL) technology has emerged as a novel interrogation modality for ligand discovery in the pharmaceutical industry. Given the increasing demand for a higher proportion of C(sp3)-hybridized centers in DEL platforms, a photore

Photochemical Approach for the Preparation of N-Alkyl/Aryl Substituted Fulleropyrrolidines: Photoaddition Reactions of Silyl Group Containing α-Aminonitriles with Fullerene C60

Lim, Suk Hyun,Oh, Jiin,Nahm, Keepyung,Noh, Sunguk,Shim, Jun Ho,Kim, Cheolhee,Kim, Eunae,Cho, Dae Won

, p. 1407 - 1420 (2019/01/30)

The photochemical reactions of C60 with N-(trimethylsilyl)methyl substituted and N-alkyl/aryl substituted α-aminonitriles were explored to evaluate the scope and reaction efficiency depending on the structural nature of amine substrates. The re

Design, synthesis, and photodegradation of silicon-containing polyureas

Hwu, Jih Ru,King, Ke Yung

, p. 3805 - 3815 (2007/10/03)

Novel N-phenyl aromatic polyureas containing bis[(N,N′- diphenylureylene)methyl]silane units in the skeleton were designed as a new type of photodegradable polymer. These materials were successfully prepared in 88-93% yields by copolymerization of bis(ani
