16951-16-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 16951-16-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,6,9,5 and 1 respectively; the second part has 2 digits, 1 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 16951-16:
(7*1)+(6*6)+(5*9)+(4*5)+(3*1)+(2*1)+(1*6)=119
119 % 10 = 9
So 16951-16-9 is a valid CAS Registry Number.

A new one-pot synthesis of 5,5-disubstituted hydantoins from diethyl acetamidomalonates and ureas

Guetschow, Michael,Hecker, Thomas,Eger, Kurt

, p. 410 - 414 (2007/10/03)

A new one-pot synthesis of 5,5-disubstituted hydantoins 3 is reported. Diethyl 2-acetamido-2-alkylmalonates were found to react with substituted ureas in the presence of sodium ethoxide to produce the 5-alkyl-5- carbamoylhydantoins 3 a-e. The reaction involves a ring contraction of intermediate 5-aminobarbituric acids to the final hydantoin derivatives. The 5-aminobarbituric acids 2 d-f were prepared from azido derivatives 6 d-f. On treatment with sodium ethoxide, 2 d-f underwent the rearrangement to afford the hydantoins 3 d-f.
