Check Digit Verification of cas no

The CAS Registry Mumber 96254-09-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,6,2,5 and 4 respectively; the second part has 2 digits, 0 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 96254-09:
(7*9)+(6*6)+(5*2)+(4*5)+(3*4)+(2*0)+(1*9)=150
150 % 10 = 0
So 96254-09-0 is a valid CAS Registry Number.

Coupling of C(sp3)-H bonds with C(sp2)-O electrophiles: mild, general and selective

Gui, Yong-Yuan,Liao, Li-Li,Sun, Liang,Zhang, Zhen,Ye, Jian-Heng,Shen, Guo,Lu, Zhi-Peng,Zhou, Wen-Jun,Yu, Da-Gang

supporting information, p. 1192 - 1195 (2017/02/05)

Herein is reported the mild and general coupling of amine/ether C(sp3)-H bonds with various kinds of C(sp2)-O electrophiles with high selectivity and efficiency. Valuable allylic/benzylic amines are generated in moderate to excellent yields. The utility of this transformation is demonstrated by a broad substrate scope (>50 examples), good functional group tolerance and facile product modification.

A Novel Convenient Synthesis of Pyridinyl and Quinolinyl Triflates and Tosylates via One-Pot Diazotization of Aminopyridines and Aminoquinolines in Solution

Kassanova, Assiya Zh.,Krasnokutskaya, Elena A.,Beisembai, Perizat S.,Filimonov, Victor D.

, p. 256 - 262 (2016/01/15)

The first effective and simple method for the direct one-pot transformation of 2-, 3-, and 4-aminopyridines, 2,6-diaminopyridines, and 2-aminoquinoline into the corresponding pyridinyl and quinolinyl trifluoromethanesulfonates and tosylates in solvents was developed. The procedure involves diazotization of the heterocyclic amines with sodium nitrite in mixed hexane-DMSO or hexane-DMF solutions in the presence of trifluoromethanesulfonic acid or p-toluenesulfonic acid.

A new one-pot solvent-free synthesis of pyridinyl tosylates via diazotization of aminopyridines

Tretyakov, Alexey N.,Krasnokutskaya, Elena A.,Gorlushko, Dmitry A.,Ogorodnikov, Vladimir D.,Filimonov, Victor D.

supporting information; experimental part, p. 85 - 87 (2011/02/25)

A new, convenient, one-pot method for the synthesis of pyridinyl tosylates is developed. The procedure involves sequential diazotization/tosylation of aminopyridines with sodium nitrite and p-toluenesulfonic acid under solvent-free conditions in a water p
