1500-24-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1500-24-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,5,0 and 0 respectively; the second part has 2 digits, 2 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1500-24:
(6*1)+(5*5)+(4*0)+(3*0)+(2*2)+(1*4)=39
39 % 10 = 9
So 1500-24-9 is a valid CAS Registry Number.

Acylation and Cyclization of N-Hydroxyisoureas by Phenyl Isocyanate
Neitzel, Michael,Zinner, Gerwalt
, p. 10 - 18 (2007/10/02)
On adding phenyl isocyanate to the N-hydroxyisoureas 1 the O-carbamoyl derivatives 4 are obtained.They can undergo ring closure to yield Δ2-1,2,4-oxadiazolin-5-one (5a), the 3-imino-1,2,4-oxadiazolidin-5-ones 5b-5e or Δ3-1,2,4-oxadia
