Check Digit Verification of cas no
The CAS Registry Mumber 118975-57-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,8,9,7 and 5 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 118975-57:
(8*1)+(7*1)+(6*8)+(5*9)+(4*7)+(3*5)+(2*5)+(1*7)=168
168 % 10 = 8
So 118975-57-8 is a valid CAS Registry Number.

Oxidation of 1-hydroxyazetidines to four-membered cyclic nitrones and β-lactams
Elburg, P. A. van,Reinhoudt, D. N.
, p. 381 - 387 (2007/10/02)
The 1-(benzyloxy)azetidines 7a-c and 16a,b were synthesized by reductive cyclization of the corresponding oximes 5a-c and 14a-d.Oxidation of the 1-hydroxyazetidines 8a-c and 17 with PbO2 afforded the corresponding four-membered cyclic nitrones 18a-c and t
