86503-25-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 86503-25-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,6,5,0 and 3 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 86503-25:
(7*8)+(6*6)+(5*5)+(4*0)+(3*3)+(2*2)+(1*5)=135
135 % 10 = 5
So 86503-25-5 is a valid CAS Registry Number.

Synthesis of 3-Ω-aminohydantoins
Ryczek, Jozef
, p. 997 - 1000 (2007/10/03)
Several 3-Ω-amino monosubstituted hydantoins have been obtained in the reaction of isocyanate of glycine ethyl ester with the appropriate aliphatic or aromatic diamine. It was found, that the 3-(aminoaryl) monosubstituted hydantoins may be diazotized and their diazonium salts may be coupled and hydrolysed without changes in the hydantoin ring.
