827-28-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 827-28-1 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 8,2 and 7 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 827-28:
(5*8)+(4*2)+(3*7)+(2*2)+(1*8)=81
81 % 10 = 1
So 827-28-1 is a valid CAS Registry Number.

Development of Imino-λ3-iodanes with Improved Reactivity for Metal-Free [2+2+1] Cycloaddition-Type Reactions

Baba, Takafumi,Takahashi, Shunsuke,Kambara, Yui,Yoshimura, Akira,Nemykin, Victor N.,Zhdankin, Viktor V.,Saito, Akio

, p. 3860 - 3864 (2017)

Aiming at the enhancement of electrophilicity of imino-λ3-iodanes, we have developed (tosylimino)pentafluorophenyl-λ3-iodane, which shows superior reactivity compared to the commonly used (tosylimino)phenyl-λ3-iodane in the [2+2+1]-type synthesis of imidazoles. (Figure presented.).

Novel oxidative, liquid-phase chlorination procedures for the preparation of (dichloroiodo)arenes from iodoarenes

Obeid,Skulski

, p. 1609 - 1615 (2007/10/03)

One improved and eight novel oxidative, liquid-phase chlorination procedures for the preparation of (dichloroiodo)arenes, ArICl2, from iodoarenes, ArI, are presented. KMnO4, activated MnO2, KCIO3, NaIO4/su

Oxidative chlorination of various lodoarenes to (dichloroiodo)arenes with chromium(vi) oxide as the oxidant j

Kazmierczak, Pawet,Skulski, Lech,Obeid, Nicolas

, p. 64 - 65 (2007/10/03)

Chromium(vi) oxide dissolved in a mixture of acetic acid with concentrated hydrochloric acid converts, at or near room temperature, iodoarenes to (dichloroiodo)arenes, in a very simple and efficient procedure.
