57966-42-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 57966-42-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,7,9,6 and 6 respectively; the second part has 2 digits, 4 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 57966-42:
(7*5)+(6*7)+(5*9)+(4*6)+(3*6)+(2*4)+(1*2)=174
174 % 10 = 4
So 57966-42-4 is a valid CAS Registry Number.

Incorporation of fluoroprolines to proctolin: Study on the effect of a fluorine atom toward peptidic conformation

, p. 286 - 293 (2008/12/22)
In spite of quite small steric perturbation, substitution of proline (Pro) in the target pentapeptide proctolin (Arg-Tyr-Leu-Pro-Thr) for (4R)- as well as (4S)-4-fluoroproline led to apparent alteration of the pyrrolidine ring structure which eventually r
