Check Digit Verification of cas no

The CAS Registry Mumber 109518-76-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,9,5,1 and 8 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 109518-76:
(8*1)+(7*0)+(6*9)+(5*5)+(4*1)+(3*8)+(2*7)+(1*6)=135
135 % 10 = 5
So 109518-76-5 is a valid CAS Registry Number.

Amino acids in the syntheses of heterocyclic systems: Syntheses and radiostability of novel biologically active triazoles containing the sulfonamide moiety

El-Sharief,Ghorab,El-Gaby,Mohamed,Ammar

, p. 316 - 323 (2007/10/03)

A number of novel triazoles 2a-f, 4, 9, 10, 12, 15; triazolothiadiazoles 6, 8, 11, 16; triazolothiadizine 5; and triazolotriazine 14 were synthesized and characterized by elemental analyses and spectral data. Six of the compounds showed antifungal activity compared with the fungicide Mycostatine. Radiosterilization of the biologically active compounds 4, 8, 9b, and 10 in the dry state may prove to be applicable at the sterile dose 25 kGy.
