333800-16-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 333800-16-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,3,3,8,0 and 0 respectively; the second part has 2 digits, 1 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 333800-16:
(8*3)+(7*3)+(6*3)+(5*8)+(4*0)+(3*0)+(2*1)+(1*6)=111
111 % 10 = 1
So 333800-16-1 is a valid CAS Registry Number.

Skeletal transformations of perfluoro-1-phenylindan under the action of antimony pentafluoride

Karpov,Mezhenkova,Platonov,Sinyakov

, p. 53 - 57 (2001)

Perfluoro-1-phenylindan (1) was obtained from perfluoroindan and pentafluorobenzene in the presence of SbF5. Compound 1 heated with antimony pentafluoride at 170°C and then treated with water gave a mixture of perfluorinated 9-methylfluorene (5

Formation of fluorene and anthracene derivatives in reactions of perfluorinated 1-alkyl-1-phenyl- and 1-alkyl-2-phenyl-1,2- dihydrocylobutabenzenes with antimony pentafluoride

Mezhenkova,Karpov,Platonov

experimental part, p. 1018 - 1025 (2011/10/19)

The reaction of perfluoro(1-methyl-1-phenyl-1,2-dihydrocyclobutabenzene) with SbF5 at 50°C, followed by hydrolysis, gave perfluoro(1-phenylindan-1-ol), while analogous reaction at 90°C afforded perfluoro[ 10-methylanthracen-9(10H)-one]. Perfluo
