6544-00-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 6544-00-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,5,4 and 4 respectively; the second part has 2 digits, 0 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 6544-00:
(6*6)+(5*5)+(4*4)+(3*4)+(2*0)+(1*0)=89
89 % 10 = 9
So 6544-00-9 is a valid CAS Registry Number.

Reaction of silicon with alcohols in autoclave

Krylova,Egorov,Nefedov

, p. 260 - 266 (2017/07/11)

A reaction of activated silicon with alcohols in an autoclave at 240—270 °C was studied. It was found that primary alcohols form tetraalkoxysilanes Si(OR)4 with high selectivity (up to 97%), while the secondary PriOH gave a mixture of compounds HSi(OPri)3, Si(OPri)4, HSi(OPri)2OSi(OPri)2H, HSi(OPri)2OSi(OPri)3, and Si(OPri)3OSi(OPri)3 with the predominance of trialkoxysilane (up to 67%). Carrying out the reaction under the indicated conditions has the advantage of experimental simplicity, reagent availability, high conversion of silicon, good isolated yields of products.
