Check Digit Verification of cas no
The CAS Registry Mumber 1284293-44-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,8,4,2,9 and 3 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1284293-44:
(9*1)+(8*2)+(7*8)+(6*4)+(5*2)+(4*9)+(3*3)+(2*4)+(1*4)=172
172 % 10 = 2
So 1284293-44-2 is a valid CAS Registry Number.

A revised approach to the synthesis of 3-acyl imidazo[l,2-a] pyridines
Gomez, Omar,Salgado-Zamora, Hector,Reyes, Alicia,Campos, Maria Elena
, p. 99 - 103 (2010)
3-Acyl imidazo[l,2-a]pyridines with no substituent at position 2 were obtained in moderate to good yields in an improved version of the Tisler protocol for the synthesis of imidazo[l,2-x]azines. It was found that yields are significantly improved if the r
