77747-74-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 77747-74-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,7,7,4 and 7 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 77747-74:
(7*7)+(6*7)+(5*7)+(4*4)+(3*7)+(2*7)+(1*4)=181
181 % 10 = 1
So 77747-74-1 is a valid CAS Registry Number.

2,4-Diaminodihydropyridines (Heterocyclic Compounds, 67. Comm.)

Schweiger, Klaus,Zigeuner, Gustav

, p. 459 - 468 (2007/10/02)

Aminolysis of 4-alkylamino- and 4-dialkylamino-2-methylthiodihydropyridines (*Hl) 1, 2 resp. under various reaction-condition leads to assymmetrically or symmetrically substituted 2,4-bisalkylamino- or 2,4-bisdialkylamino- and 2-alkylamino-4-dialkylamino- or 2-dialkylamino-4-alkylaminodihydropyridines 3, 4, 5, 6 resp.On treatment with alkali only the aminogroup in pos.4 of the pyridines 3, 4, 5, 6 is hydrolyzed and 4-hydroxy-2-aminopyridines 9 are formed.Different substituted 2,4-diaminodihydropyridines 3, 4, 5, 6 can also be synthesized by reaction of 4-hydroxy-2-aminopyridines (*HCl) 9 with amines.Also the aminolysis of 4-alkylamino- and 4-dialkylaminodihydropyridinthiones 7, 8 resp. is described. - Keywords: 2-Alkylamino-4-dialkylamino-5,6-dihydropyridines, synthesis; Alkyl- and arylaminopyridine derivatives, reaction with prim. and sec. amines; Aminolysis of alkyl-, and arylaminopyridine derivatives; 2,4-Bisalkylamino-5,6-dihydropyridines, synthesis; 2,4-Bisdialkylamino-5,6-dihydropyridines, synthesis; 2-Dialkylamino-4-alkylamino-5,6-pyridines, synthesis.
