Check Digit Verification of cas no

The CAS Registry Mumber 307307-84-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,0,7,3,0 and 7 respectively; the second part has 2 digits, 8 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 307307-84:
(8*3)+(7*0)+(6*7)+(5*3)+(4*0)+(3*7)+(2*8)+(1*4)=122
122 % 10 = 2
So 307307-84-2 is a valid CAS Registry Number.

experimental part, p. 498 - 509 (2012/03/08)

This paper describes our recent efforts to design and synthesise potent and selective PDE5 inhibitors and the use of in vitro predictors of clearance, absorption and permeability to maximise the potential for dose-proportional pharmacokinetics and good oral bioavailability in man. Optimisation of the preclinical profile resulted in the identification of UK-369003 (19a) and its nomination as a clinical candidate. The clinical pharmacokinetic and safety profile has enabled us to progress the compound to test its efficacy in patients with lower urinary tract symptoms (LUTS) associated with benign prostatic hyperplasia (BPH) and a paper describing its efficacy has recently been published.2,3.

, p. 4623 - 4637 (2007/10/03)

The design and synthesis of a series of 6-methylidene penems containing [6,5]-fused bicycles (thiophene, imidazole, or pyrazle-fused system) as novel class A, B, and C β-lactamase inhibitors is described. These penems proved to be potent inhibitors of the TEM-1 (class A) and AmpC (class C) β-lactamases and less so against the class B metallo-β-lactamase CcrA. Their in vitro and in vivo activities in combination with piperacillin are discussed. On the basis of the crystallographic structures of a serine-bound reaction intermediate of 2 with SHV-1 (class A) and GC1 (class C) enzymes, compounds 14a-1 were designed and synthesized. Penems are proposed to form a seven-membered 1,4 thiazepine ring in both class A and C β-lactamases. The interaction energy calculation for the enzyme-bound intermediates favor the formation of the C7 R enantiomer over the S enantiomer of the 1,4-thiazepine in both β-lactamases, which is consistent with those obtained from the crystal structure of 2 with SHV-1 and GC1.
