Check Digit Verification of cas no

The CAS Registry Mumber 79014-37-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,9,0,1 and 4 respectively; the second part has 2 digits, 3 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 79014-37:
(7*7)+(6*9)+(5*0)+(4*1)+(3*4)+(2*3)+(1*7)=132
132 % 10 = 2
So 79014-37-2 is a valid CAS Registry Number.

Functionalization of non-activated C-H bonds in ketones and imines with HF/SbF5/CCl4

Thibaudeau, Sébastien,Martin-Mingot, Agnès,Jouannetaud, Marie-Paule,Jacquesy

, p. 6643 - 6649 (2002)

Reaction of cyclic ketones 2-6 and imines 15-17 in HF/SbF5 in presence of CCl4 yield hydroxy or fluoroderivatives, hydride abstraction occurring at a site located far from the functional group. Whereas ketones 2-5 yield only hydroxy derivatives, through cyclic carboxonium ion, imines 15, 16 N-protonated in the media conditions give only fluoroderivatives 18, 19, respectively, after quenching with HF-pyridine. Ring contraction is operative when starting from large membered ring ketones 24 and 25, and imine 26, leading to a mixture of hydroxy or fluoro cyclohexanones and/or cycloheptanones.
