193091-62-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 193091-62-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,3,0,9 and 1 respectively; the second part has 2 digits, 6 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 193091-62:
(8*1)+(7*9)+(6*3)+(5*0)+(4*9)+(3*1)+(2*6)+(1*2)=142
142 % 10 = 2
So 193091-62-2 is a valid CAS Registry Number.

Addition of Organolithiums to the (R)-O-(1-Phenylbutyl)hydroxylamine (ROPHy) Oxime of Cinnamaldehyde. Asymmetric Synthesis of α-Aminoacids
Moody, Christopher J.,Lightfoot, Andrew P.,Gallagher, Peter T.
, p. 659 - 660 (1997)
A new asymmetric synthesis of α-aminoacids is described in which the key step is the diastereoselective addition of organolithium reagents to (R)-O-(1-phenylbutyl) cinnamaldoxime.
