Check Digit Verification of cas no
The CAS Registry Mumber 31458-45-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,1,4,5 and 8 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 31458-45:
(7*3)+(6*1)+(5*4)+(4*5)+(3*8)+(2*4)+(1*5)=104
104 % 10 = 4
So 31458-45-4 is a valid CAS Registry Number.

Selective hydrolysis of 2,4-diaminopyrimidine systems: A theoretical and experimental insight into an old rule

Hydrolysis of the amino groups in condensed 2,4-diaminopyrimidine systems (1) has been used as a common method for the synthesis of oxo-substituted pyrimidines. In particular, the treatment with 6 M HCl usually yields exclusively the 2-amino-4-oxopyrimidine isomer (2). During our work we found that the hydrolysis of the amino groups present in some condensed 2,4-diaminopyrimidine systems unexpectedly afforded exclusively the 4-amino-2-oxopyrimidine isomer (3). In this paper, we present the experimental work and ab initio calculations carried out to understand this discrepancy. As a part of such study, eight compounds containing a 2,4-diaminopyrimidine moiety were calculated in gas phase and in aqueous solution, and some acid hydrolyses were reexamined. Results showed that the presence, of an electron-donating nitrogen linked to C6 of the 2,4-diaminopyrimidine ring changes the preferred hydrolysis site to yield the 4-amino-2-oxopyrimidine isomer.
