Check Digit Verification of cas no
The CAS Registry Mumber 199807-77-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,9,8,0 and 7 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 199807-77:
(8*1)+(7*9)+(6*9)+(5*8)+(4*0)+(3*7)+(2*7)+(1*7)=207
207 % 10 = 7
So 199807-77-7 is a valid CAS Registry Number.

Phosphorylation of 2-azabicyclo[2.2.1]hept-5-ene and 2-hydroxy-2- azabicyclo[2.2.1]hept-5-ene systems: Synthesis and mechanistic study
Sousa, Carlos A. D.,Vale, M. Luisa C.,Rodriguez-Borges, Jose E.,Garcia-Mera, Xerardo
experimental part, p. 2546 - 2551 (2011/01/12)
The endo and exo isomers of (±)-methyl 2-hydroxy-2-azabicyclo[2.2.1] hept-5-ene-3-carboxylates and the in situ-prepared endo and exo isomers of (±)-methyl 2-azabicyclo[2.2.1]hept-5-ene-3-carboxylate were treated with diphenylphosphinic chloride (OPClPh2) and chlorodiphenylphosphine (ClPPh2) to afford the corresponding phosphorylated bicycles. The structure of all these compounds was unequivocally determined by NMR spectroscopy and mass spectrometry, and, based on the results obtained, a mechanistic scheme for the phosphorylation reaction of these adducts to afford the corresponding phosphorylbicycles is proposed.
