Check Digit Verification of cas no
The CAS Registry Mumber 5744-71-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,7,4 and 4 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 5744-71:
(6*5)+(5*7)+(4*4)+(3*4)+(2*7)+(1*1)=108
108 % 10 = 8
So 5744-71-8 is a valid CAS Registry Number.

Synthesis and reactions of silylated and stannylated 1,2-azoles
Calle,Cuadrado,Gonzalez-Nogal,Valero
, p. 1949 - 1958 (2007/10/03)
Silicon or tin 4-metalated pyrazoles and isoxazoles are synthesized by silyl- or stannylcupration from 4-haloazoles. On the other hand, 5-metalated pyrazoles are prepared by reaction of 5-un-substituted pyrazoles with LDA and subsequent treatment with chlorosilanes and chlorostannanes. Furthermore, starting from 5-unsubstituted 4-halopyrazoles and applying both methodologies, 4,5-dimetalated pyrazoles bearing silyl groups different from trimethylsilyl or tributylstannyl groups are obtained. Some regioselective ipso-substitutions are also studied.
