Check Digit Verification of cas no

The CAS Registry Mumber 125414-29-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,5,4,1 and 4 respectively; the second part has 2 digits, 2 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 125414-29:
(8*1)+(7*2)+(6*5)+(5*4)+(4*1)+(3*4)+(2*2)+(1*9)=101
101 % 10 = 1
So 125414-29-1 is a valid CAS Registry Number.

Amino Acids and Peptides; 70. Optically Active α-Amino Acids, N-Boc-Aminoaldehydes and α-Amino-β-hydroxy Acids from 2,3-Epoxy Alcohols

Schmidt, Ulrich,Respondek, Mathias,Lieberknecht, Albrecht,Werner, Juergen,Fischer, Peter

, p. 256 - 261 (2007/10/02)

Trichloroacetimidic esters of 2,3-epoxy alcohols are transformed into oxazolines 5 and dihydrooxazines 6, respectively, depending on the structure of the educts and the catalyst.The five-membered ring compounds 5 are transformed into erythro-α-amino-β-hydroxy acids (60-70percent from epoxy alcohols) via axazolidinones 11, 12, and 13. α-Amino acids and α-substituted α-amino acids 10 as well as the corresponding aldehydes 9 are obtained from the dihydrooxazines 6 (50-60percent from epoxy alcohols).
