Uses
Used in Cancer Chemotherapy:
Deaza-Aminopterin is utilized as a chemotherapy agent for its potential to treat various types of cancer. It has demonstrated promising results in preclinical studies, particularly for conditions such as acute lymphoblastic leukemia, non-Hodgkin's lymphoma, and solid tumors. Deaza-Aminopterin's mechanism of action involves blocking the synthesis of nucleic acids, which is essential for cancer cell growth and proliferation.
Check Digit Verification of cas no
The CAS Registry Mumber 18921-68-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,8,9,2 and 1 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 18921-68:
(7*1)+(6*8)+(5*9)+(4*2)+(3*1)+(2*6)+(1*8)=131
131 % 10 = 1
So 18921-68-1 is a valid CAS Registry Number.

Chemistry and Antitumor Evaluation of Selected Classical 2,4-Diaminoquinazoline Analogues of Folic Acid
Hynes, J.B.,Harmon, S.J.,Floyd, G.G.,Farrington, M.,Hart, L.D.,et al.
, p. 209 - 215 (2007/10/02)
A series of six 2,4-diaminoquinazoline analogues of folic acid which bear close structural resemblance to methotrexate, 1a, were synthesized by unequivocal routes.Three of these have not been described previously, while complete structural characterizatio
