Check Digit Verification of cas no

The CAS Registry Mumber 295-29-4 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 2,9 and 5 respectively; the second part has 2 digits, 2 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 295-29:
(5*2)+(4*9)+(3*5)+(2*2)+(1*9)=74
74 % 10 = 4
So 295-29-4 is a valid CAS Registry Number.

SYNTHESIS OF AZA-CROWN COMPOUNDS BY INTRAMOLECULAR CYCLIZATION OF ω-AMINO ACIDS

Mikhura, I. V.,Formanovskii, A. A.

, p. 205 - 212 (1992)

A method for the synthesis of aza-crown compounds by the intramolecular cyclization of ω-amino acids with subsequent reduction of the lactam to a macrocyclic amine was developed. 1,8-Diazacyclotetradecane and 1,8-dioxa-4,11-diazacyclotetradecane was synthesized in preparative yields.The structural assignments were made using the IR, 1H and 13C NMR, and mass spectra.
