77329-14-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 77329-14-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,7,3,2 and 9 respectively; the second part has 2 digits, 1 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 77329-14:
(7*7)+(6*7)+(5*3)+(4*2)+(3*9)+(2*1)+(1*4)=147
147 % 10 = 7
So 77329-14-7 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
