Check Digit Verification of cas no
The CAS Registry Mumber 174811-45-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,4,8,1 and 1 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 174811-45:
(8*1)+(7*7)+(6*4)+(5*8)+(4*1)+(3*1)+(2*4)+(1*5)=141
141 % 10 = 1
So 174811-45-1 is a valid CAS Registry Number.

Optimisation, scope and limitations of the synthesis of 5-aminoindolizines from oxazolo[3,2-a]pyridinium salts
Tielmann,Hoenke
, p. 261 - 265 (2007/10/03)
In this letter, we report on our efforts to optimise the reaction conditions and to explore the scope and limitations of the preparation of 5-aminoindolizines starting from oxazolo[3,2-a]pyridinium salts and different amines to evaluate the utility for co
