Check Digit Verification of cas no

The CAS Registry Mumber 41772-29-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,1,7,7 and 2 respectively; the second part has 2 digits, 2 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 41772-29:
(7*4)+(6*1)+(5*7)+(4*7)+(3*2)+(2*2)+(1*9)=116
116 % 10 = 6
So 41772-29-6 is a valid CAS Registry Number.

Comparison of preparation methods of N-arylsulfinyl-1,4-benzoquinone monoimines

Avdeenko,Konovalova,Santalova

, p. 231 - 236 (2008/12/20)

Advantages and shortcomings were discussed of three procedures for preparation N-arylsulfinyl-1,4-benzoquinone imines: the reaction of arenesulfenyl chlorides with 1,4-benzoquinone oximes, the oxidation of N-arylthio-1,4-benzoquinone imines, and the reaction of arylsulfinyl chlorides with p-aminophenols followed by oxidation. A series of new N-arylsulfinyl-1,4- benzoquinone imines was obtained.

Synthesis and 13C NMR spectra of N-substituted p-quinonimines: III. N-arylthio- and N-arylsulfonyl-1,4-benzoquinonimines with enhanced electron-donor character of quinoid ring

Pirozhenko,Avdeenko,Yusina,Konovalova

, p. 1121 - 1128 (2007/10/03)

Incorporation of alkyl substituents into quinonimine fragments of N-arylthio- and N-arylsulfonyl-1,4-benzoquinonimines results in virtually equal changes in the chemical shifts of the carbon atoms from this fragment compared to those of unsubstituted and
