31408-40-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 31408-40-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,1,4,0 and 8 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 31408-40:
(7*3)+(6*1)+(5*4)+(4*0)+(3*8)+(2*4)+(1*0)=79
79 % 10 = 9
So 31408-40-9 is a valid CAS Registry Number.

Preparation of 2,5-disubstituted pyrimidines from vinamidinium salts and synthesis of novel disulfane derivatives

Rafiee Samani, Ziba,Mehranpour, Abdolmohammad,Hasaninejad, Alireza

supporting information, p. 2150 - 2156 (2020/03/10)

Novel pyrimidine derivatives were prepared from the reaction of 2-substituted 1,3-bis(dimethylamino)-trimethinium salts with thiourea or guanidine in the presence of ethyl-diisopropylamine in ethanol at reflux, and also some 5-substituted pyrimidine-2-thi

A general and highly efficient method for the construction of aryl-substituted N-heteroarenes

Liu, Chun,Han, Na,Song, Xiaoxiao,Qiu, Jieshan

supporting information; experimental part, p. 5548 - 5551 (2011/02/19)

A general, simple and highly efficient method has been developed for the Pd(OAc)2-catalyzed ligand-free and aerobic Suzuki reaction of N-heteroaryl halides, which is strongly dependent on the molecular structure of solvent. A general, simple and highly efficient method has been developed for the Pd(OAc)2-catalyzed ligand-free and aerobic Suzuki reaction of N-heteroaryl halides including 2-pyridyl bromides, 3-pyridyl bromides, 3-quinolyl bromides, 5-pyrimidyl bromides and 2-pyrazyl chloride, which is strongly dependent on the molecular structure of solvent.

A NEW AND FACILE SYNTHESIS OF 5-ARYLPYRIMIDINES AND 4-ARYLPYRAZOLES

Kano, Shinzo,Yuasa, Yoko,Shibuya, Shiroshi,Hibino, Satoshi

, p. 1079 - 1082 (2007/10/02)

A condensation of 2-aryl-3-(methylthio)acroleins (3a)-(3e), a new masked form of arylmalondialdehydes, with amidines yielded the corresponding 5-arylpyrimidines (4a)-(4k).Similarly, the reaction of 3 with N-substituted hydrazines gave the corresponding 1-
