903568-77-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 903568-77-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,0,3,5,6 and 8 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 903568-77:
(8*9)+(7*0)+(6*3)+(5*5)+(4*6)+(3*8)+(2*7)+(1*7)=184
184 % 10 = 4
So 903568-77-4 is a valid CAS Registry Number.

Drug and Imaging Agent Delivery Compositions and Methods

-

Paragraph 0121; 0122, (2013/07/31)

A multi-arm, star-shaped polymer composition can be configured for drug delivery and imaging applications in vivo. The star polymer architecture can be synthesized using living radical polymerization techniques, including reversible addition-fragmentation chain transfer and macromolecular design via the interchange of xanthates with a broad range of reaction conditions and functional groups. The star-shaped polymeric carriers can be tailored for preferential delivery of chemotherapeutics into the tumor-draining lymphatics via subcutaneous, peritumoral or intratumoral injections. The carriers can be loaded with the chemotherapeutic agents from about 10% to about 25% w/w. In addition, the carriers can be loaded with imaging agents from about 5% to about 10% w/w. The molecular weights of the polymeric carriers can be about 40 kDa to about 130 kDa. The chemotherapeutics can be cisplatin, geldanamycin or nitric oxide-donating prodrugs. The imaging agent can be a near-infrared dye, such as IR820.
