42221-50-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 42221-50-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,2,2,2 and 1 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 42221-50:
(7*4)+(6*2)+(5*2)+(4*2)+(3*1)+(2*5)+(1*0)=71
71 % 10 = 1
So 42221-50-1 is a valid CAS Registry Number.

Allosteric Modifiers of Hemoglobin. 1. Design, Synthesis, Testing, and Structure-Allosteric Activity Relationship of Novel Hemoglobin Oxygen Affinity Decreasing Agents

Randad, Ramnarayan S.,Mahran, Mona A.,Mehanna, Ahmed S.,Abraham, Donald J.

, p. 752 - 757 (2007/10/02)

Three isomeric series of 2-(aryloxy)-2-methylpropionic acids were prepared and studied for their ability to decrease the oxygen affinity of human hemoglobin A.The isomeric aryloxy groups included 4-methyl>phenoxy, 4-(arylacetamido)phenoxy, and 4-methyl>phenoxy.A total of 20 compounds were synthesized and tested.Structure-activity relationships are presented.Several of the new compounds were found to be strong allosteric effectors of hemoglobin.The two most active compounds are 2-methyl>phenoxy>-2-methylpropionic acid and the corresponding 3,5-dimethyl derivative.The latter two compounds have been compared to other known potent allosteric effectors in the same assay and show greater activity.Both compounds also exhibit a right shift in the oxygen equilibrium curve when incubated with whole blood.The new compounds may be of interest in clinical or biological areas that require or would benefit from a reversal of depleted oxygen supply (i.e., ischemia, stroke, tumor radiotherapy, blood storage, blood substitutes, etc.).They are also structurally related to several marketed antilipidemic agents.
