Check Digit Verification of cas no

The CAS Registry Mumber 197020-64-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,7,0,2 and 0 respectively; the second part has 2 digits, 6 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 197020-64:
(8*1)+(7*9)+(6*7)+(5*0)+(4*2)+(3*0)+(2*6)+(1*4)=137
137 % 10 = 7
So 197020-64-7 is a valid CAS Registry Number.

Heteroatom transfer to alkenes by N-protected-oxaziridines: New reaction pathways and products

Armstrong, Alan,Edmonds, Ian D.,Swarbrick, Martin E.

, p. 2207 - 2210 (2005)

N-Alkoxycarbonyl- and N-carboxamido-oxaziridines are shown to react with aromatic alkenes to give epoxide, aziridine or hydro-oxidation products, in ratios depending on the oxaziridine structure. Chiral oxaziridines can effect epoxidation and hydro-oxidation with promising levels of asymmetric induction.
