Check Digit Verification of cas no

The CAS Registry Mumber 1243692-69-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,4,3,6,9 and 2 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1243692-69:
(9*1)+(8*2)+(7*4)+(6*3)+(5*6)+(4*9)+(3*2)+(2*6)+(1*9)=164
164 % 10 = 4
So 1243692-69-4 is a valid CAS Registry Number.

Nitrone protecting groups for enantiopure N-hydroxyamino acids: Synthesis of N-terminal peptide hydroxylamines for chemoselective ligations

Medina, S. Irene,Wu, Jian,Bode, Jeffrey W.

supporting information; experimental part, p. 3405 - 3417 (2010/08/21)

The synthesis of enantiopure N-benzylidene nitrones of N-hydroxy-α- amino acids and their incorporation using standard Fmoc-based peptide chemistry into solid-supported peptide chains is described. Deprotection and resin cleavage affords N-terminal peptid
