Check Digit Verification of cas no

The CAS Registry Mumber 107116-09-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,7,1,1 and 6 respectively; the second part has 2 digits, 0 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 107116-09:
(8*1)+(7*0)+(6*7)+(5*1)+(4*1)+(3*6)+(2*0)+(1*9)=86
86 % 10 = 6
So 107116-09-6 is a valid CAS Registry Number.

1,3-Bis(2-benzoylphenyl)-1,1,3,3-tetramethyldisiloxane

Wiese, Dietmar,Wannagat Ulrich,Thewalt, Ulf,Debaerdemaeker, Tony

, p. 873 - 878 (2007/10/02)

Attempts to prepare 9,9-dimethyl-9-sila-10(9H)-anthracenone (4a) from dimethylphenyl-2-tolylsilane (5) or 2-bromobenzoic acid as starting compounds via 2-(dimethylphenylsilyl)benzoyl chloride (11a) by condensation with tin tetrachloride resulted in high yields of the title compound 14a.Determination of its structure was only possible by X-ray analysis, determination of the course of the reaction by variation with 2-benzoyl chloride (11b) and mass spectroscopical investigation of the resulting isomeric mixture of bistetramethyldisiloxanes 14b,b',b''.
