113493-41-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 113493-41-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,3,4,9 and 3 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 113493-41:
(8*1)+(7*1)+(6*3)+(5*4)+(4*9)+(3*3)+(2*4)+(1*1)=107
107 % 10 = 7
So 113493-41-7 is a valid CAS Registry Number.

Oxidative magnesiation of halogenopyridines: Introduction of electrophilic substituents to the pyridine moiety under the Barbier condition

Sugimoto, Osamu,Yamada, Shigeru,Tanji, Ken-Ichi

, p. 3355 - 3357 (2002)

Oxidative magnesiation of halogenopyridines was carried out using active magnesium prepared by the reduction of magnesium chloride, to give pyridinylmagnesium halides, which were treated with electrophiles to afford the corresponding pyridine derivatives.

Preparation of nitrogen-containing π-deficient heteroaromatic Grignard reagents: Oxidative magnesiation of nitrogen-containing π-deficient halogenoheteroaromatics using active magnesium

Sugimoto, Osamu,Yamada, Shigeru,Tanji, Ken-Ichi

, p. 2054 - 2057 (2007/10/03)

The oxidative magnesiation of nitrogen-containing π-deficient halogenoheteroaromatics using active magnesium was accomplished. Both magnesiation followed by addition of a carbonyl compound (Grignard reaction) and magnesiation in the presence of a carbonyl compound (Barbier reaction) were carried out to afford the corresponding product. Especially, the latter method enabled fused halogenodiazines such as 4-chloro-1-phenyl-1H-pyrazolo[3,4-d]pyrimidine or 2-chloroquinoxaline to magnesiate at a mild temperature (-20 to 30 °C).
