151503-25-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 151503-25-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,1,5,0 and 3 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 151503-25:
(8*1)+(7*5)+(6*1)+(5*5)+(4*0)+(3*3)+(2*2)+(1*5)=92
92 % 10 = 2
So 151503-25-2 is a valid CAS Registry Number.

Efficient desulfurization of 2-thiopyrimidine nucleosides to the corresponding 4-pyrimidinones
Kuimelis,Nambiar
, p. 3813 - 3816 (2007/10/02)
A procedure is described for the preparation of 2'-deoxy-4-pyrimidinone (dH2U) and 2'-deoxy-5-methyl-4-pyrimidinone (dH2T) nucleosides. The key transformation is a nearly quantitative desulfurization of the corresponding 2-thio analo
