23849-52-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 23849-52-7 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, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 23849-52:
(7*2)+(6*3)+(5*8)+(4*4)+(3*9)+(2*5)+(1*2)=127
127 % 10 = 7
So 23849-52-7 is a valid CAS Registry Number.

Racemates and enantiomers of 5,5-disubstituted hexahydropyrimidines
Knabe,Biwersi
, p. 31 - 32 (2007/10/02)
The racemic and the enantiomeric hexahydropyrimidin-2-ones 1a-1e can be reduced by LiAlH4 in high yields to the racemic and the enantiomeric hexahydropyrimidines 2a-2e. The enantiomers of 2a-2e show the same direction of rotations as the starti
