Check Digit Verification of cas no

The CAS Registry Mumber 110562-21-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,0,5,6 and 2 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 110562-21:
(8*1)+(7*1)+(6*0)+(5*5)+(4*6)+(3*2)+(2*2)+(1*1)=75
75 % 10 = 5
So 110562-21-5 is a valid CAS Registry Number.

New methods and reagents in organic synthesis. 92. A stereoselective synthesis of tilivalline and its analogs

Mori, Shigehiro,Ohno, Tomoyasu,Harada, Hiroshi,Aoyama, Toyohiko,Shioiri, Takayuki

, p. 5051 - 5070 (2007/10/02)

Tilivalline (1a), a metabolite from Klebsiella pneumoniae var. oxytoca, and its derivatives 1 have been efficiently and stereoselectively synthesized from diphenyl phosphorazidate, the 2-oxazoline 2, the L-proline derivatives 5, and indole; the key step is a Mannich type intramolecular cyclization accompanied with completely stereoselective introduction of indole. Furthermore, 11-substituted 5H- pyrrolo[2,1-c][1,4]benzodiazepin-5-ones (16) have been also synthesized from the acetal amide 9a and various nucleophiles by the use of this new Mannich type cyclization.
