75398-22-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 75398-22-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,5,3,9 and 8 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 75398-22:
(7*7)+(6*5)+(5*3)+(4*9)+(3*8)+(2*2)+(1*2)=160
160 % 10 = 0
So 75398-22-0 is a valid CAS Registry Number.

Racemic and Optically Active Hydantoins from Disubstituted Cyanoacetic Acids
Knabe, Joachim,Wunn, Wolfgang
, p. 538 - 543 (2007/10/02)
Starting from the chiral disubstituted cyanoacetic acids 1 the racemates and some enantiomers of the 5,5-disubstituted hydantoins 6 and of the 3-methylhydantoins 7 are synthesized via the isocyanates 3.Their absolute configurations are determined.
