Check Digit Verification of cas no

The CAS Registry Mumber 108179-79-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,8,1,7 and 9 respectively; the second part has 2 digits, 7 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 108179-79:
(8*1)+(7*0)+(6*8)+(5*1)+(4*7)+(3*9)+(2*7)+(1*9)=139
139 % 10 = 9
So 108179-79-9 is a valid CAS Registry Number.

New chiral polysiloxanes prepared from derivatives of (+)- or (-)-2-phenyl-3-butehoic acid, (r)-l-hepten-3-ol and (r)-l-cyclohexyl-2-propen-1-ol

A series of new polysiloxanes containing chiral side groups has been prepared. These polymers were prepared by hydrosilylating chiral alkene derivatives onto polyhydromethylsiloxane. The alkene derivatives were prepared from (+) or (-)-2-phenyl-3-butenoic acid, (R)-1-hepten-3-ol and (R)-1-cyclohexyl-2-propen-1-ol. Polysiloxanes containing racemic substituents were also prepared fron derivatives of racemic 3-buten-2-ol. The polysiloxanes containing biphenyl carboxylate derivatives (11a-13a) had liquid crystalline properties. These polymers were prepared for use as stationary phases for capillary gas and supercritical fluid chromatography.
