23261-20-3 Usage

Biological Activity

val-083 is a bi-functional alkylating agent, with potential antitumor activity.val-083 can cross the blood brain barrier and appears to be selective for tumor cells. val-083 alkylates and crosslinks dna which ultimately inhibit the proliferation of cancer cells. val-083 does not show cross-resistance to other conventional chemotherapeutic agents. the half-life of val-083 in the brain is long. val-083 has been assessed in multiple studies as chemotherapy in the treatment of newly diagnosed and recurrent brain tumors.

Check Digit Verification of cas no

The CAS Registry Mumber 23261-20-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,3,2,6 and 1 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 23261-20:
(7*2)+(6*3)+(5*2)+(4*6)+(3*1)+(2*2)+(1*0)=73
73 % 10 = 3
So 23261-20-3 is a valid CAS Registry Number.
