Check Digit Verification of cas no

The CAS Registry Mumber 144951-90-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,4,9,5 and 1 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 144951-90:
(8*1)+(7*4)+(6*4)+(5*9)+(4*5)+(3*1)+(2*9)+(1*0)=146
146 % 10 = 6
So 144951-90-6 is a valid CAS Registry Number.

A convenient synthetic method for N-perfluoroalkanesulfonyl sulfilimines and sulfoximides

Zhu, Shi-Zheng,Zhang, Jie,Xu, Bin

, p. 81 - 84 (1995)

Reaction of perfluoroalkanesulfonyl amides with dialkyl sulfides or sulfoxides in the presence of stoichiometric amounts of lead tetra-acetate gave N-perfluoroalkanesulfonyl sulfilimines or N-perfluoroalkanesulfonyl sulfoximides, respectively, in moderate to good yield. - Keywords: Synthesis; Perfluoroalkanesulfonyl amides; N-perfluoroalkanesulfonyl sulfilimine; Sulfoximide

Unexpected formation of the novel fluorinated diazenes

Zhu, Shizheng,Jin, Guifang,He, Ping,Xu, Yong,Huang, Qichen

, p. 8717 - 8719 (2003)

Fluoroalkanesulfonyl azides reacted with morpholine giving unexpectedly N-fluoroalkanesulfonyl-N-morpholino diazenes, which were fully characterized by using spectral methods and X-ray diffraction analysis.

Study on the reactions of fluoroalkanesulfonyl azides with pyridine and its derivatives

Xu, Yong,Zhu, Shizheng

, p. 13725 - 13734 (1999)

The thermal reactions of fluoroalkanesulfonyl azides R(f)SO2N3 1 with pyridine and its derivatives have been investigated in detail. In many cases, N-fluoroalkanesulfonyl pyridinium imides Y+-N'SO2R(f) (Y: pyridine, 3- picoline, 3,5-lutidine and quinoline) and the hydrogen abstraction products R(f)SO2NH2 were obtained. 2-Picoline and 4-picoline reacted with 1 to give R(f)SO2NH2 exclusively. Interestingly, in the reaction of azides 1c IC2F4OC2F4SO2N3 with 4-picoline or quinoline, the ω-iodine of the azide was substituted to form ArC2F4OC2F4SO2NH2.

Determination of pKa values of fluoroalkanesulfonamides and investigation of their nucleophilicity

Zhang, Cheng-Pan,Wang, Zong-Ling,Chen, Qing-Yun,Zhang, Chun-Tao,Gu, Yu-Cheng,Xiao, Ji-Chang

scheme or table, p. 761 - 766 (2010/08/06)

The pKa values of a series of fluoroalkanesulfonylamides were measured by potentiometric titration. Different kinds of alkyl halides and tosylates were employed to investigate the nucleophilicity of fluoroalkanesulfonylamides. Fluoroalkanesulfonylamides with longer fluoroalkyl chain have weaker nucleophilicity.
