100890-40-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 100890-40-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,0,8,9 and 0 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 100890-40:
(8*1)+(7*0)+(6*0)+(5*8)+(4*9)+(3*0)+(2*4)+(1*0)=92
92 % 10 = 2
So 100890-40-2 is a valid CAS Registry Number.

Ketene-S,N-acetals as Synthons for Heterocycles New Synthesis of Pyrimidinones
Gelbin, Michael,Martin, Dieter
, p. 753 - 766 (2007/10/02)
Ketene-S,N-acetals of type 1, 2 reacted with isocyanates to 5-cyano-uracils 3 and 5-cyano-pyrimidin-2-ones 4,5.Reaction of these with N nucleophiles was investigated furnishing 6-amino-pyrimidinones 6 as well as condensed pyrimidin-2-ones 7-10 and 13.Cyan
