Check Digit Verification of cas no
The CAS Registry Mumber 17928-31-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,7,9,2 and 8 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 17928-31:
(7*1)+(6*7)+(5*9)+(4*2)+(3*8)+(2*3)+(1*1)=133
133 % 10 = 3
So 17928-31-3 is a valid CAS Registry Number.

Rate studies of the acid-catalyzed solvolysis of eight-membered cyclosilazoxanes
Lasocki, Zygmunt,Witekowa, Malgorzata
, p. 27 - 33 (2007/10/02)
The solvolysis of N-phenyl-1,1,3,3,5,5,7,7-octamethyl-1,3,5,7-tetrasila-2-aza-4,6,8-trioxacyclooctane (1) and N,N'-diphenyl-1,1,3,3,5,5,7,7-octamethyl-1,3,5,7-tetrasila-2,6-diaza-4,8-dioxacyclooctane (II) in methanol/water in the presence of an acetate buffer is a pseudo-first-order process, subject to general acid-catalysis.The catalytic rate constants have been determined spectrophotometrically for the solvolysis of I.The ring cleavage is slower than that of analogous six-membered cyclosilazoxanes, but the catalytic mode and the solvent isotope effect indicate a close mechanistic similarity between the solvolyses of six- and eight-membered rings.
