Check Digit Verification of cas no

The CAS Registry Mumber 203574-75-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,3,5,7 and 4 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 203574-75:
(8*2)+(7*0)+(6*3)+(5*5)+(4*7)+(3*4)+(2*7)+(1*5)=118
118 % 10 = 8
So 203574-75-8 is a valid CAS Registry Number.

A convenient synthesis of 5-substituted 1-[1- (diethoxyphosphoryl)alkyl]-1H-1,2,3-triazoles

Sikora, Dorota,Gajda, Tadeusz

, p. 1215 - 1222 (1998)

5-Substituted 1-[1(diethoxyphosphoryl)alkyl]-1H-1,2,3-triazoles were prepared in good yields (61-83%) via thermal 1,3-dipolar cycloaddition of diethyl 1-azidoalkylphosphonates and 2-oxoalkylidene triphenylphosphoranes.

Cycloaddition reactions of azidomethyl phosphonate with acetylenes and enamines. Synthesis of triazoles

Louerat, Frederic,Bougrin, Khalid,Loupy, Andre,De Retana, Ana M. Ochoa,Pagalday, Jaione,Palacios, Francisco

, p. 161 - 170 (2007/10/03)

β-Functionalized alkyltriazoles can be efficiently prepared under solvent-free conditions, eventually by coupling with microwave activation. Cycloadditions of azides and poorly activated acetylenes or enamines are thus possible with interesting selectivity in the latter case.
