6904-60-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 6904-60-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,9,0 and 4 respectively; the second part has 2 digits, 6 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 6904-60:
(6*6)+(5*9)+(4*0)+(3*4)+(2*6)+(1*0)=105
105 % 10 = 5
So 6904-60-5 is a valid CAS Registry Number.

REACTION OF OCTAMETHYLCYCLOTETRASILOXANE AND PERMETHYLOLIGOSILOXANES WITH ACYL CHLORIDES IN THE PRESENCE OF CoCl2

Basenko, S. V.,Ogorodnikova, E. I.,Vitkovskii, V. Yu.,Mirskov, R. G.,Voronkov, M. G.

, p. 79 - 83 (2007/10/02)

Octamethylcyclotetrasiloxane is cleaved quantitatively by acetyl chloride (1:1 molar ratio) in the presence of anhydrous CoCl2 in acetonitrile at room temperature to form primarily α-chloro-ω-acetoxyoligodimethylsiloxanes nOCOCH3 (n = 0-3; yield, 60-65percent)>.In the presence of an equimolar amount of trimethylacetoxysilane of hexamethyldisiloxane, the major reaction products are α-methyl-ω-acetoxyoligodimethylsiloxanes nOCOCH3 (n = 4-6; yield, 65-70percent)>.
