877269-03-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 877269-03-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,7,7,2,6 and 9 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 877269-03:
(8*8)+(7*7)+(6*7)+(5*2)+(4*6)+(3*9)+(2*0)+(1*3)=219
219 % 10 = 9
So 877269-03-9 is a valid CAS Registry Number.

The synthesis of novel heteroaryl-fused 7,8,9,10-tetrahydro-6H-azepino[1,2- a]indoles, 4-oxo-2,3-dihydro-1H-[1,4]diazepino[1,7-a]indoles and 1,2,4,5-tetrahydro-[1,4]oxazepino[4,5-a]indoles. Effective inhibitors of HCV NS5B polymerase

, p. 6654 - 6662 (2011/11/06)

Three synthetic approaches have been developed that allow efficient access to novel heteroaryl fused indole ring systems, including: 7,8,9,10-tetrahydro- 6H-azepino[1,2-a]indoles, 4-oxo-2,3-dihydro-1H-[1,4]diazepino[1,7-a]indoles and 1,2,4,5-tetrahydro-[1,4]oxazepino[4,5-a]indoles. Each strategy is fully exemplified and the relative merits and limitations of the approaches are discussed. The hepatitis C virus (HCV) non-structural 5B (NS5B) polymerase inhibitory activities of select examples from each molecular class are briefly presented.
