Check Digit Verification of cas no

The CAS Registry Mumber 215675-49-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,5,6,7 and 5 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 215675-49:
(8*2)+(7*1)+(6*5)+(5*6)+(4*7)+(3*5)+(2*4)+(1*9)=143
143 % 10 = 3
So 215675-49-3 is a valid CAS Registry Number.

First synthesis of the N(1)-bulky substituted imidazole 3-oxides and their complexation with hexafluoroacetone hydrate

Mloston, Grzegorz,Jasinski, Marcin

body text, p. 162 - 175 (2011/06/19)

Synthesis of new 2-unsubstituted imidazole 3-oxides bearing bulky substituents at the N(1) atom, based on the condensation of appropriate alkylamines, formaldehyde, and corresponding a-(hydroxyimino)ketone, is described. Treatment of imidazole 3-oxides with hexafluoroacetone hydrate (HFAH) yields crystalline 1:1 complexes in nearly quantitative yields. Heating of isolated complexes possessing phenyl ring at the C(4) atom of imidazole ring, results in their isomerization into imidazol-2-ones in fair yields. The formation of analogous complexes of HFAH with other azole N-oxides is also described. ARKAT-USA, Inc.
