Check Digit Verification of cas no

The CAS Registry Mumber 1333481-05-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,3,3,4,8 and 1 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1333481-05:
(9*1)+(8*3)+(7*3)+(6*3)+(5*4)+(4*8)+(3*1)+(2*0)+(1*5)=132
132 % 10 = 2
So 1333481-05-2 is a valid CAS Registry Number.

Design, synthesis and biological evaluation of brain-specific glucosyl thiamine disulfide prodrugs of naproxen

Fan, Wei,Wu, Yong,Li, Xian-Kun,Yao, Nian,Li, Xun,Yu, Yong-Guo,Hai, Li

, p. 3651 - 3661 (2011/11/06)

Glucosyl derivates exhibited favorable distribution to the brain. However, bidirectional transport of glucose transporter 1 might decrease concentrations of the prodrugs in brain before the release of parent drugs. To overcome this defect, glucosyl thiamine disulfide prodrugs 1a-1c incorporating naproxen were designed and synthesized. Furthermore, prodrug 2 and 3 were also prepared as control. The favorable physicochemical properties of these prodrugs were verified by stability and metabolism studies. Results from the in vivo distribution study indicated that 1a-1c, and 1b in particular, significantly increased the level of naproxen in brain when compared to 2 and 3. The study suggested glucosyl thiamine disulfide was a promising carrier to enhance the brain bioavailability of central nervous system active drugs.
