280574-88-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 280574-88-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,8,0,5,7 and 4 respectively; the second part has 2 digits, 8 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 280574-88:
(8*2)+(7*8)+(6*0)+(5*5)+(4*7)+(3*4)+(2*8)+(1*8)=161
161 % 10 = 1
So 280574-88-1 is a valid CAS Registry Number.

Intramolecular carbolithiation reactions of chiral alpha-amino-organolithium species.

Ashweek, Neil J,Coldham, Iain,Snowden, David J,Vennall, Graham P

, p. 195 - 207 (2002)

Enantiomerically enriched alpha-amino-organolithium species, in which the lithium atom is attached to a stereogenic carbon centre, have been found to be chemically stable at room temperature in a solvent of very low polarity and undergo intramolecular car
