Check Digit Verification of cas no

The CAS Registry Mumber 28223-71-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,8,2,2 and 3 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 28223-71:
(7*2)+(6*8)+(5*2)+(4*2)+(3*3)+(2*7)+(1*1)=104
104 % 10 = 4
So 28223-71-4 is a valid CAS Registry Number.

SYNTHETIC UTILIZATION OF α-AMINO-γ-BROMOBUTYRIC ACID IN THE PREPARATION OF NON-CODED AMINO ACIDS; IR STUDY OF HOMOSERINE

Prochazka, Zdenko,Smolikova, Jorga,Malon, Petr,Jost, Karel

, p. 2935 - 2946 (2007/10/02)

α-Amino-γ-bromobutyric acid and its derivatives were utilized in the preparation of some non-coded (non-proteinogenic) amino acids and their derivatives.The bromine atom was replaced by hydrogen, hydroxyl, iodine and nitro, amino, and thiocyanato groups.Homolanthionine was prepared by two methods.Homoserine has been shown to exist in three crystalline modifications whose differences in the IR spectra indicate conformational changes.
