Check Digit Verification of cas no
The CAS Registry Mumber 18419-59-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,8,4,1 and 9 respectively; the second part has 2 digits, 5 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 18419-59:
(7*1)+(6*8)+(5*4)+(4*1)+(3*9)+(2*5)+(1*9)=125
125 % 10 = 5
So 18419-59-5 is a valid CAS Registry Number.

Treatment of alkyltriethoxysilanes with Amberlyst 15 cation-exchange resin in the presence of hexamethyldisiloxane
Hasegawa, Isao,Sakka, Sumio
, p. 31 - 36 (2007/10/02)
Methyltriethoxysilane and ethyltriethoxysilane were treated with Amberlyst 15 cation-exchange resin in the presence of hexamethyldisiloxane at 40 deg C.The reaction involves partial or full replacement of the ethoxyl group by trimethylsiloxyl to give RSi(OEt)n(OSiMe3)3-n (n=0, 1, 2).The degree of substitution depends mainly on the ratio in which hexamethyldisiloxane and alkyltriethoxysilane are mixed.The nature of alkyl group in an alkyltriethoxysilane had little effect on the degree of substitution at a given mixing ratio.
