21768-51-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 21768-51-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,1,7,6 and 8 respectively; the second part has 2 digits, 5 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 21768-51:
(7*2)+(6*1)+(5*7)+(4*6)+(3*8)+(2*5)+(1*1)=114
114 % 10 = 4
So 21768-51-4 is a valid CAS Registry Number.

Synthesis and Characterization of N-Substituted Valines and their Phenyl- and Pentafluorophenyl-thiohydantoins
Rydberg, Per,Luening, Bjoern,Wachtmeister, Carl Axel,Toernqvist, Margareta
, p. 813 - 817 (2007/10/02)
The phenylthiohydantoins of racemic N-methyl-, N-(2-hydroxethyl)- and N-phenyl-valine as well as the pentafluorophenylthiohydantoins of these acids and of L-valine have been synthesized by reactions with phenyl isothiocynate and pentafluorophenyl isothioc
