198836-45-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 198836-45-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,8,8,3 and 6 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 198836-45:
(8*1)+(7*9)+(6*8)+(5*8)+(4*3)+(3*6)+(2*4)+(1*5)=202
202 % 10 = 2
So 198836-45-2 is a valid CAS Registry Number.

A facile method for the N-alkylated of α-amino esters

Bowman, W. Russell,Coghlan, Daniel R.

, p. 15787 - 15798 (1997)

Monoalkylation of the α-amino group of α-amino acid derivatives can be facilitated using 2 -and 4-nitrophenylsulfonamide intermediates. The nitrophenylsulfonamides of α-amino esters can be alkylated using an equimolar amount of carbonate base and a variety of alkyl bromides. Ready removal of the nitrophenylsulfonyl group is facilitated by S(N)Ar reaction between the N-alkylated sulfonamide and phenylthiolate to give the N-alkylated α-amino esters in good yield without racemisation of the chiral α-centres.
