169298-50-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 169298-50-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,9,2,9 and 8 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 169298-50:
(8*1)+(7*6)+(6*9)+(5*2)+(4*9)+(3*8)+(2*5)+(1*0)=184
184 % 10 = 4
So 169298-50-4 is a valid CAS Registry Number.

Synthesis of some new imidazo[1,2-a]pyrimidin-5(1H)-ones as potential antineoplastic agents
Badawey,Kappe
, p. 1003 - 1006 (1995)
Some substituted imidazo[1,2-a]pyrimidin-5(1H)-ones have been synthesized via the reaction of 2-aminoimidazole sulfate with some β-keto esters, diethyl ethoxymethylenemalonate and ethyl ethoxymethylenecyanoacetate. Several compounds were screened for thei
