Check Digit Verification of cas no

The CAS Registry Mumber 2441-21-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,4,4 and 1 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 2441-21:
(6*2)+(5*4)+(4*4)+(3*1)+(2*2)+(1*1)=56
56 % 10 = 6
So 2441-21-6 is a valid CAS Registry Number.

New route to permethylcyclosiloxanes

Basenko,Klyba,Voronkov

, p. 1368 - 1370 (2007/10/03)

A new method for preparing permethylcyclosiloxanes, based on reaction of 1,1,3,3-tetramethyldisiloxane with iodine (molar ratio 1:1) in inert organic solvents (alkanes, alkyl halides, benzene) is proposed. The products of the reaction react with ethoxytrimethylsilane and tetramethoxysilane in hexamethyldisiloxane to give respectively pentamethyldisiloxane and products of successive substitution of the methoxy groups in Si(OMe)4 by Me2SiHO. A probable scheme of their formation is discussed.
