160154-99-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 160154-99-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,0,1,5 and 4 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 160154-99:
(8*1)+(7*6)+(6*0)+(5*1)+(4*5)+(3*4)+(2*9)+(1*9)=114
114 % 10 = 4
So 160154-99-4 is a valid CAS Registry Number.

4-Hydrazono-oxazolidin-2-ones from 2-substituted glycolamidrazones
Geffken,Holst
, p. 821 - 824 (2007/10/02)
Hydrazinolysis of the glycolimidates 2 smoothly affords the glycolamidrazones 3, which are condensed with acetone or benzaldehyde to give hydrazono derivatives of type 4. Cyclic carbonylation of 4a-h with 1,1'-carbonyldiimidazole yields 4-hydrazono-oxazol
