Check Digit Verification of cas no

The CAS Registry Mumber 103879-58-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,3,8,7 and 9 respectively; the second part has 2 digits, 5 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 103879-58:
(8*1)+(7*0)+(6*3)+(5*8)+(4*7)+(3*9)+(2*5)+(1*8)=139
139 % 10 = 9
So 103879-58-9 is a valid CAS Registry Number.

Programmable oligomers for minor groove DNA recognition

Doss, Raymond M.,Marques, Michael A.,Foister, Shane,Chenoweth, David M.,Dervan, Peter B.

, p. 9074 - 9079 (2006)

The four Watson-Crick base pairs of DNA can be distinguished in the minor groove by pairing side-by-side three five-membered aromatic carboxamides, imidazole (Im), pyrrole (Py), and hydroxypyrrole (Hp), four different ways. On the basis of the paradigm of

Widely Exploited, Yet Unreported: Regiocontrolled Synthesis and the Suzuki–Miyaura Reactions of Bromooxazole Building Blocks

Solomin, Vitalii V.,Radchenko, Dmytro S.,Slobodyanyuk, Evgeniy Y.,Geraschenko, Oleksandr V.,Vashchenko, Bohdan V.,Grygorenko, Oleksandr O.

, p. 2884 - 2898 (2019/03/07)

An approach to synthesis of 2-, 4-, and 5-bromooxazoles is described. The method was optimized, and its scope was extended to all three isomeric parents, as well as various alkyl- and aryl-substituted bromooxazoles. It was found that direct regiocontrolled lithiation followed by reaction with electrophilic bromine source was common for all substrates and led exclusively to the target substituted 2-, 4- and 5-bromooxazoles on multigram scale. The utility of the multipurpose building blocks obtained in this work was demonstrated in the Suzuki–Miyaura cross-coupling reaction under parallel synthesis conditions.
