205-50-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 205-50-5 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 2,0 and 5 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 205-50:
(5*2)+(4*0)+(3*5)+(2*5)+(1*0)=35
35 % 10 = 5
So 205-50-5 is a valid CAS Registry Number.

Pd-catalyzed tandem C-H azidation and N-N bond formation of arylpyridines: A direct approach to pyrido[1,2-b ]indazoles

Zheng, Qing-Zhong,Feng, Peng,Liang, Yu-Feng,Jiao, Ning

supporting information, p. 4262 - 4265 (2013/09/12)

A novel Pd-catalyzed nitrogenation of arylpyridines via C-H azidation has been developed. Direct C-N and N-N formations are achieved for this N-atom incorporation transformation using azides as the N-atom source. This method provides an alternatively concise approach for the construction of bioactively important pyrido[1,2-b]indazoles.

REACTIONS OF SUBSTITUTED PYRIDINIUM N-IMINES WITH BENZYNE: SYNTHESES OF PYRIDOINDAZOLES AND RELATED COMPOUNDS

Yamashita, Yoshiro,Hayashi, Takashi,Masumura, Mitsuo

, p. 1133 - 1136 (2007/10/02)

Reactions of benzyne with several pyridinium N-imines were examined. 2-o-Aminophenylpyridine derivatives 6, pyridoindazoles (7), indazoloquinoline (17), and indazoloisoquinoline (18) were obtained by the reactions of benzyne with the
