Check Digit Verification of cas no

The CAS Registry Mumber 28873-61-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,8,8,7 and 3 respectively; the second part has 2 digits, 6 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 28873-61:
(7*2)+(6*8)+(5*8)+(4*7)+(3*3)+(2*6)+(1*1)=152
152 % 10 = 2
So 28873-61-2 is a valid CAS Registry Number.

Reactions of diazoalkanes with isocyanates. Synthesis of imidazolidine-2,4-diones, oxindoles, and oxazolidinones

Fulton, Janet B.,Warkentin, John

, p. 1177 - 1184 (2007/10/02)

Thermolysis of a 5,5-dialkyl-Δ3-1,3,4-oxadiazolin-2-one in nitrobenzene containing an aryl isocyanate at 150 deg C affords a 1,3-diaryl-5,5-dialkyl imidazolidine-2,4-dione, an N-arylcarbamoyl-3,3-dialkyloxindole, and a 3-aryl-2-arylimino-5,5-dialkyl-1,3-oxazolidin-4-one.Those products arise from attack of a diazoalkane, generated in situ from the oxadiazolinone by thermal cycloreversion, on the isocyanate function.Two imidazolidine diones, three oxazolidinones, and 14 oxindoles were prepared.
