75419-87-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 75419-87-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,5,4,1 and 9 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 75419-87:
(7*7)+(6*5)+(5*4)+(4*1)+(3*9)+(2*8)+(1*7)=153
153 % 10 = 3
So 75419-87-3 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.
