33875-36-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 33875-36-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,3,8,7 and 5 respectively; the second part has 2 digits, 3 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 33875-36:
(7*3)+(6*3)+(5*8)+(4*7)+(3*5)+(2*3)+(1*6)=134
134 % 10 = 4
So 33875-36-4 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.
