Check Digit Verification of cas no
The CAS Registry Mumber 189322-86-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,9,3,2 and 2 respectively; the second part has 2 digits, 8 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 189322-86:
(8*1)+(7*8)+(6*9)+(5*3)+(4*2)+(3*2)+(2*8)+(1*6)=169
169 % 10 = 9
So 189322-86-9 is a valid CAS Registry Number.

Oxidation of 2-phenylhydrazono-γ-butyrolactone: A novel ring expansion rearrangement leading to tetrahydro-1,3-oxazine-2,4-dione derivatives
Barton, Derek H. R.,Liu, Wansheng
, p. 571 - 572 (2007/10/03)
2-Hydroxy-2-phenylazo-γ-butyrolactone 3a, prepared from oxidation of phenylhydrazone 1a, either decomposes to form α-keto-γ-butyrolactone 2a in 80% yield or rearranges to tetrahydro-1,3-oxazine-2,4-dione derivative 4a in 95% yield under different conditio
