99841-22-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 99841-22-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,9,8,4 and 1 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 99841-22:
(7*9)+(6*9)+(5*8)+(4*4)+(3*1)+(2*2)+(1*2)=182
182 % 10 = 2
So 99841-22-2 is a valid CAS Registry Number.

Novel Br?nsted acidic ionic liquids catalyzed one-pot reaction of highly green regioselective thiocyanation of N-containing aromatic and heteroaromatic compounds at room temperature

Sajjadifar, Sami,Mansouri, Ghobad,Nikseresht, Ahmad,Kakaei Azani, Fatemeh

, p. 294 - 307 (2018/02/06)

In this method, a novel Br?nsted acidic ionic liquid silica-supported pyridinium sulfonic acid thiocyanate {SiO2@[Pyridine-SO3H]SCN} and sulfonic acid-functionalized pyridinium chloride {[PSA]Cl} were easily synthesized and character

1-methyl-3-(2-(Sulfooxy)Ethyl)-1H-imidazol-3-ium thiocyanate as a novel, green, and efficient bronsted acidic ionic liquid-promoted regioselective thiocyanation of aromatic and heteroaromatic compounds at room temperature

Sajjadifar, Sami,Hosseinzadeh, Hossein,Ahmadaghaee, Saied,Rezaee Nezhad, Eshagh,Karimian, Saaid

, p. 333 - 342 (2014/03/21)

An efficient and simple method for the preparation of 1-methyl-3-(2- (sulfooxy)ethyl)-1H-imidazol-3-ium thiocyanate ([Msei]SCN) as a Bronsted acidic ionic liquid (BAIL) is described, and it is used in the highly efficient regioselective thiocyanation of aromatic and heteroaromatic compounds via a green and simple protocol. [Msei]SCN as a novel IL and thiocyanation agent, H2O2 as a mild and environmentally friendly oxidant, and H2O:ethanol(1:4) as a solvent were used. This procedure provided the target thiocyanates in high yield and very short reaction time. [Supplementary materials are available for this article.

Silica-bonded vanadic acid [SiO2-VO(OH)2] as a heterogeneous and recyclable catalyst for thiocyanation of organic compounds in aqueous media at room temperature

Khazaei, Ardeshir,Zolfigol, Mohammad Ali,Safaiee, Maliheh,Mokhlesi, Mohammad,Donyadari, Elmira,Shiri, Morteza,Kruger, Hendrik Gerhardus

experimental part, p. 34 - 38 (2012/08/28)

Silica vanadic acid (in which vanadium oxytrichloride has been supported on silica) is applied as an efficient, reusable and heterogeneous catalyst for the thiocyanation of heterocycles, substituted anilines (electron-rich and electron-deficient) and N-su
