1028560-09-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1028560-09-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,2,8,5,6 and 0 respectively; the second part has 2 digits, 0 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1028560-09:
(9*1)+(8*0)+(7*2)+(6*8)+(5*5)+(4*6)+(3*0)+(2*0)+(1*9)=129
129 % 10 = 9
So 1028560-09-9 is a valid CAS Registry Number.

A facile synthesis of 2-(N-alkylamino)-pyrimidin-4-one derivatives
Li, Jizhen,Kou, Jingping,Luo, Xuyang,Fan, Erkang
, p. 2761 - 2763 (2008/09/19)
Substituted 2-(N-alkylamino)-pyrimidin-4-ones were synthesized from N-alkyl β-amino acid esters starting with guanidinylation using Pbf-activated thiourea. The six-membered pyrimidinones were obtained in good yields via intramolecular cyclization during T
