68049-16-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 68049-16-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,8,0,4 and 9 respectively; the second part has 2 digits, 1 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 68049-16:
(7*6)+(6*8)+(5*0)+(4*4)+(3*9)+(2*1)+(1*6)=141
141 % 10 = 1
So 68049-16-1 is a valid CAS Registry Number.

Microwave-assisted synthesis of phenylpyrimidine derivatives via Suzuki-Miyaura reactions in water

Le, Yi,Zhang, Yan,Wang, Qin,Rao, Nian,Li, Dan,Liu, Li,Ouyang, Guiping,Yan, Longjia

supporting information, (2021/02/21)

An efficient method was developed to prepare biphenylpyrimidine scaffolds via a Suzuki-Miyaura coupling reaction. In this procedure, the products were synthesized under microwave irradiation in water and analogues of biguanidine were employed as ligands.

Palladium-Catalyzed Regioselective C-H Bond ortho-Acetoxylation of Arylpyrimidines

Zheng, Xiaojian,Song, Bingrui,Xu, Bin

supporting information; experimental part, p. 4376 - 4380 (2010/10/04)

An efficient and regioselective palladium-catalyzed ortho C-H acetoxylation reaction was developed to afford, ortho monoacetoxylated arylpyrimidmes in good to excellent yields by using cupric trifluoroacetate as a cocatalyst. A wide variety of oxygenated
