62196-39-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 62196-39-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,2,1,9 and 6 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 62196-39:
(7*6)+(6*2)+(5*1)+(4*9)+(3*6)+(2*3)+(1*9)=128
128 % 10 = 8
So 62196-39-8 is a valid CAS Registry Number.

Preparation of Heteroarenecarbonitriles by Reaction of Haloheteroarenes with Potassium Cyanide Catalyzed by Sodium p-Toluenesulfinate

Miyashita, Akira,Suzuki, Yumiko,Ohta, Kiyono,Higashino, Takeo

, p. 345 - 356 (2007/10/02)

Several heteroarenecarbonitriles were prepared by reaction of haloheteroarenes with potassium cyanide catalyzed by sodium p-toluenesulfinate (1) or sodium methanesulfinate (2).In the reaction pathway, the cyanation proceeds through the formation of the su

Purines. VIII. Reactions of 1-Benzoyl-1,6-dihydro-9-phenyl-9H-purine-6-carbonitrile (9-Phenylpurine Reissert Compound) with Acid, Bases, and Electrophiles

Tanji, Ken-ichi,Sato, Susumu,Miyashita, Akira,Oishi, Etsuo,Higashino, Takeo

, p. 187 - 189 (2007/10/02)

1-Benzoyl-1,6-dihydro-9-phenyl-9H-purine-6-carbonitrile (1, 9-phenylpurine Reissert compound) was hydrolyzed in an acid medium to give the ring fission product of the pyrimidine ring (3, 4).Alkaline hydrolysis of 1 gave 9-phenyl-9H-purine (2) and benzoic acid (5).The anion of 1 generated from 1 and sodium hydride in tetrahydrofuran underwent aromatization, resulting in the formation of 9-phenyl-9H-purine-6-carbonitrile (6) together with 2.The reaction of 1 with aromatic aldehydes in the presence of sodium hydride proceeded to give the 6-purinylmethyl benzoates (8a-c), together with 2 and 9.On the other hand, the reaction of 1 with 2,4-dinitrochlorobenzene in the presence of sodium hydride failed to give the corresponding 6-arylpurine, and the aromatization product 6 was obtained.Keywords - 9H-purine; Reissert compound anion; 9H-purin-6-ylmethyl benzoate
