15851-81-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 15851-81-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,5,8,5 and 1 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 15851-81:
(7*1)+(6*5)+(5*8)+(4*5)+(3*1)+(2*8)+(1*1)=117
117 % 10 = 7
So 15851-81-7 is a valid CAS Registry Number.

Design and synthesis of novel pyridopyrimidine derivatives with anchoring non-coplanar aromatic extensions of EGFR inhibitory activity

The present study describes the synthesis of three series of 4-substituted pyridopyrimidin derivatives 4a-h, 5a-d. 6a-d, starting from 2-amino-6-(4-methoxyphenyl)-4-(4-(substituted) phenyl)nicotinonitrile 2a-d via the reaction with N,N-dimethyl-N-' substi

Change of the favored routes of EI MS fragmentation when proceeding from N1, N1-dimethyl-N2-arylformamidines to 1,1,3,3-tetraalkyl-2-arylguanidines: Substituent effects

Raczynska, Ewa D.,Makowski, Mariusz,Gal, Jean-Francois,Maria, Pierre-Charles

body text, p. 762 - 771 (2011/09/12)

Although series of N1, N1-dimethyl-N 2-arylformamidines and of 1,1,3,3-tetraalkyl-2-arylguanidines are structurally analogous and similar electron-ionization mass spectral fragmentationmay be expected, they display important differences in the favored routes of fragmentation andconsequently in substituent effectsonion abundances. In the caseof formamidines, the cyclizationelimination process (initiated by nucleophilic attack of the N-amino atom on the 2-position of the phenyl ring) and formation of the cyclic benzimidazolium [M-H]+ ions dominates, whereas the loss of the NR2 group ismore favored for guanidines. In order to gain information on the most probable structures of the principal fragments, quantum-chemical calculations were performed on a selected set. A good linear relation between log{I[M-H]+I [M]+?} and σR+ constants of substituent at para position in the phenyl ring occurs solely for formamidines (r = 0.989). In the case of guanidines, this relation is not significant (r = 0.659). A good linear relation is found between log{I[M-NMe2]+/I [M]+?} and σp+ constants (r = 0.993). Copyright
