253353-09-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 253353-09-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,5,3,3,5 and 3 respectively; the second part has 2 digits, 0 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 253353-09:
(8*2)+(7*5)+(6*3)+(5*3)+(4*5)+(3*3)+(2*0)+(1*9)=122
122 % 10 = 2
So 253353-09-2 is a valid CAS Registry Number.

Efficient synthesis of a novel 4-hydroxy-2,3-dioxocyclobut-1-enyl group containing amino acids

, p. 1663 - 1666 (1999)

matrix presented Syntheses of novel amino acids possessing a squaryl group, 1-3, in an optically active form are described. The syntheses of 1-3 were conducted by a concise route involving (1) an aldol addition of an enolate derived from Gly, L-Asp, or L-Glu to diisopropyl squarate (4) and (2) an efficient decarboxylation of the aldol adducts based on the electron-withdrawing property of the squaryl group. Introducing N-protected group to 2 and 3 and peptide formation reactions are also described.
