674776-41-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 674776-41-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,7,4,7,7 and 6 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 674776-41:
(8*6)+(7*7)+(6*4)+(5*7)+(4*7)+(3*6)+(2*4)+(1*1)=211
211 % 10 = 1
So 674776-41-1 is a valid CAS Registry Number.

Stereoselective synthesis of both enantiomers of N-Boc-α-aryl- γ-aminobutyric acids
Camps, Pelayo,Munoz-Torrero, Diego,Sanchez, Laura
, p. 311 - 321 (2007/10/03)
Esterification of racemic α-aryl-β-cyanopropionic acid chlorides with either (R)- or (S)-N-phenylpantolactam as the chiral auxiliary in the presence of Et3N resulted in the predominant formation of (αR,3′R)- or (αS,3′S)-configured pantolactam c
