Check Digit Verification of cas no

The CAS Registry Mumber 109442-40-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,9,4,4 and 2 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 109442-40:
(8*1)+(7*0)+(6*9)+(5*4)+(4*4)+(3*2)+(2*4)+(1*0)=112
112 % 10 = 2
So 109442-40-2 is a valid CAS Registry Number.

1,1′-carbonyldiimidazole (CDI) mediated coupling and cyclization to generate [1,2,4]triazolo[4,3-a]pyridines

Baucom, Kyle D.,Jones, Sian C.,Roberts, Scott W.

, p. 560 - 563 (2016)

An operationally efficient CDI mediated tandem coupling and cyclization reaction to generate [1,2,4]triazolo[4,3-a]pyridines has been reported. The reaction conditions and scope were investigated, and the methodology was demonstrated in batch mode as well

Synthesis of 1,2,4-Triazolo[4,3-a]pyridines and Related Heterocycles by Sequential Condensation and Iodine-Mediated Oxidative Cyclization

Li, Ertong,Hu, Zhiyuan,Song, Lina,Yu, Wenquan,Chang, Junbiao

, p. 11022 - 11027 (2016/07/27)

A facile and efficient approach to access 1,2,4-triazolo[4,3-a]pyridines and related heterocycles has been accomplished through condensation of readily available aryl hydrazines with corresponding aldehydes followed by iodine-mediated oxidative cyclizatio
