Check Digit Verification of cas no

The CAS Registry Mumber 112507-71-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,2,5,0 and 7 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 112507-71:
(8*1)+(7*1)+(6*2)+(5*5)+(4*0)+(3*7)+(2*7)+(1*1)=88
88 % 10 = 8
So 112507-71-8 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 (2007/10/02)

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.
