Notclassified
Check Digit Verification of cas no
The CAS Registry Mumber 138-32-9 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 1,3 and 8 respectively; the second part has 2 digits, 3 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 138-32:
(5*1)+(4*3)+(3*8)+(2*3)+(1*2)=49
49 % 10 = 9
So 138-32-9 is a valid CAS Registry Number.

Paragraph 0129-0131, (2020/08/30)
The invention relates to a meso-porous silicon oxide nanoparticle-based controlled release system and a preparation method thereof, and concretely relates to a meso-porous silicon oxide-based nanoparticle for controlled release, a controlled release system containing the nanoparticle, and a preparation method and a kit of the nanoparticle. The nanoparticle contains a phenyl borate functionalized meso-porous silicon oxide nanoparticle and a surface functionalized nanoparticle hole plugging agent which can be combined with phenyl borate. When no substrate exists, a nanometer silicon oxide system in the invention can realize zero early release; and after the substrate is added, a meso-porous tunnel plugged by the nanoparticle is opened in order to realize controlled release of a content. The method has the advantages of simple material synthesis, adjustable composition, and realization of responses to different substrates and different concentrations.
