Check Digit Verification of cas no
The CAS Registry Mumber 138000-88-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,8,0,0 and 0 respectively; the second part has 2 digits, 8 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 138000-88:
(8*1)+(7*3)+(6*8)+(5*0)+(4*0)+(3*0)+(2*8)+(1*8)=101
101 % 10 = 1
So 138000-88-1 is a valid CAS Registry Number.

SYNTHESIS OF 2H-IMIDAZOLE 1-OXIDES AND STABLE NITROXYL RADICALS BASED ON THEM
Kirilyuk, I. A.,Grigor'ev, I. A.,Volodarskii, L. B.
, p. 1871 - 1879 (2007/10/02)
2H-Imidazole 1-oxides containing an aldonitrone group in the heterocyclic ring are obtained by the condensation of hydroxyiminomethyl ketones with ketones and ammonium acetate.Their oxidation with lead dioxide in methanol gives stable nitroxyl radicals -
