Check Digit Verification of cas no

The CAS Registry Mumber 74212-41-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,4,2,1 and 2 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 74212-41:
(7*7)+(6*4)+(5*2)+(4*1)+(3*2)+(2*4)+(1*1)=102
102 % 10 = 2
So 74212-41-2 is a valid CAS Registry Number.

Metal-Free meta-Selective Alkyne Oxyarylation with Pyridine N-Oxides: Rapid Assembly of Metyrapone Analogues

Chen, Xiangyu,Ruider, Stefan A.,Hartmann, Rolf W.,González, Leticia,Maulide, Nuno

supporting information, p. 15424 - 15428 (2016/12/03)

An efficient metal-free oxyarylation of electron-poor alkynes with pyridine N-oxides has been developed. This transformation affords meta-substituted pyridines analogous to the drug metyrapone in high regioselectivities. Density functional theory (DFT) ca

Conversion of Pyridines and Quinolines into Pyridazines and Pyrazoles

Baradarani, M. Mehdi,Joule, John A.

, p. 72 - 77 (2007/10/02)

3-Phenacylpyridinium and 3-phenacylquinolinium methiodides are shown to react with hydrazine-potassium hydroxide and hydrazine respectively to give 4-alkyl-6-phenylpyridazines and 4-(2-aminobenzyl)-6-phenylpyridazines respectively. 3-Benzoylpyridinium met
