121031-01-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 121031-01-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,1,0,3 and 1 respectively; the second part has 2 digits, 0 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 121031-01:
(8*1)+(7*2)+(6*1)+(5*0)+(4*3)+(3*1)+(2*0)+(1*1)=44
44 % 10 = 4
So 121031-01-4 is a valid CAS Registry Number.

Reductive activation of conformationally-constrained, anticancer drug delivery systems

Gharat, Laxmikant,Visser, Petra,Brummelhuis, Mathijn,Guiles, Ronald,Chikhale, Prashant

, p. 444 - 456 (2007/10/03)

Redox-active substituents were used to modulate reduction potentials in conformationally-constrained, drug delivery systems. The extent of drug delivery was proportional to the degree of reductive activation, which was influenced by the electronic properties of the substituents. Such reductively-activated carrier systems can be used to achieve controlled drug delivery to bioreductive regions in hypoxic solid tumors.
