23849-74-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 23849-74-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,3,8,4 and 9 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 23849-74:
(7*2)+(6*3)+(5*8)+(4*4)+(3*9)+(2*7)+(1*4)=133
133 % 10 = 3
So 23849-74-3 is a valid CAS Registry Number.

Cyclic ureas, I: Racemates and enantiomers of hexahydropyrimidin-2-ones: Syntheses, configurations and sedative-hypnotic activity
Knabe,Buch,Biwersi
, p. 79 - 84 (1993)
The racemates and the enantiomers of the hexahydropyrimidin-2-ones 2a-2e which can be regarded as cyclic ureas are obtained from the racemates and the enantiomers of the barbiturates 1a-1e by reduction with LiAlH4/AlCl3. The enantiom
