118743-82-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 118743-82-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,8,7,4 and 3 respectively; the second part has 2 digits, 8 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 118743-82:
(8*1)+(7*1)+(6*8)+(5*7)+(4*4)+(3*3)+(2*8)+(1*2)=141
141 % 10 = 1
So 118743-82-1 is a valid CAS Registry Number.

Enantioselective Synthesis of Optically Pure (R)- and (S)-β-Lysine via Nitrone Cycloaddition
Keirs, David,Moffat, David,Overton, Karl
, p. 654 - 655 (1988)
Optically pure (R)- and (S)-β-lysines have been obtained via cycloaddition of chiral nitrone (4) to vinyl acetate, followed by facile chromatographic separation of the four resulting acetates (5) into two pairs of C-5 epimers and conversion of each pair i
