Check Digit Verification of cas no
The CAS Registry Mumber 7781-23-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,7,8 and 1 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 7781-23:
(6*7)+(5*7)+(4*8)+(3*1)+(2*2)+(1*3)=119
119 % 10 = 9
So 7781-23-9 is a valid CAS Registry Number.

HSAB driven chemoselectivity in alkylation of uracil derivatives. A high yielding preparation of 3-alkylated and unsymmetrically 1,3-dialkylated uracils
Gambacorta, Augusto,Farah, Mohamed Elmi,Tofani, Daniela
, p. 12615 - 12628 (2007/10/03)
A qualitative hardness scale (N134) has been found for the conjugated bases of 2-methoxy-4(3H)-pyrimidinones 1-3 and applied to high yielding chemoselective N3 methylation, ethylation and benzylation reactions. Removal of the 2-methoxy group followed by a second alkylation affords unsymmetrically 1,3-disubstituted uracils.
