Check Digit Verification of cas no
The CAS Registry Mumber 109183-72-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,9,1,8 and 3 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 109183-72:
(8*1)+(7*0)+(6*9)+(5*1)+(4*8)+(3*3)+(2*7)+(1*2)=124
124 % 10 = 4
So 109183-72-4 is a valid CAS Registry Number.

A Versatile Method for the Synthesis of (S)- or (R)-Cycloalkylglycines, (S)- or (R)-N-Heterocyclic and α,β-Unsaturated N-Heterocyclic α-Amino Acids
Pauly, Regine,Sasaki, N. Andre,Potier, Pierre
, p. 237 - 240 (2007/10/02)
Two different types of cyclic α-amino acids, cycloalkylglycines and N-heterocyclic α-amino acids, were prepared in optically pure form from the same chiral synthon 1-(R) (or 1-(S)) simply by altering the quantity or type of base required for anion formation.Elaboration of the heterocyclic intermediate 3 provided α,β-unsaturated N-heterocyclic α-amino acids.
