75866-43-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 75866-43-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,5,8,6 and 6 respectively; the second part has 2 digits, 4 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 75866-43:
(7*7)+(6*5)+(5*8)+(4*6)+(3*6)+(2*4)+(1*3)=172
172 % 10 = 2
So 75866-43-2 is a valid CAS Registry Number.

THE FIRST CHEMICAL CONVERSION OF L-PROLINE TO L-GLUTAMIC ACID
Yoshifuji, Shigeyuki,Matsumoto, Hideyo,Tanaka, Ken-ichi,Nitta, Yoshihiro
, p. 2963 - 2964 (1980)
The ruthenium tetroxide oxidation of N-acyl-L-proline esters gave the corresponding L-pyroglutamic acid derivatives in good yields with no appreciable racemization, which lead to the first chemical conversion of L-proline to L-glutamic acid.
