454685-21-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 454685-21-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,5,4,6,8 and 5 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 454685-21:
(8*4)+(7*5)+(6*4)+(5*6)+(4*8)+(3*5)+(2*2)+(1*1)=173
173 % 10 = 3
So 454685-21-3 is a valid CAS Registry Number.

Design, synthesis, and structure-activity relationship of 6-alkynylpyrimidines as potent adenosine kinase inhibitors

Adenosine (ADO) is an extracellular signaling molecule within the central and peripheral nervous system. Its concentration is increased at sites of tissue injury and inflammation. One of the mechanisms by which antinociceptive and antiinflammatory effects of ADO can be enhanced consists of inhibition of adenosine kinase (AK), the primary metabolic enzyme for ADO. Novel nonnucleoside AK inhibitors based on 4-amino-6-alkynylpyrimidines were prepared, and the importance of the length of the linker at the 5-position for high affinity AK inhibition was demonstrated. Compounds with 2- and 3-atom linkers were the most potent AK inhibitors. Optimization of their physicochemical properties led to 31a and 37a that effectively reduced pain and inflammation in animal models.
