Check Digit Verification of cas no

The CAS Registry Mumber 17159-70-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,7,1,5 and 9 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 17159-70:
(7*1)+(6*7)+(5*1)+(4*5)+(3*9)+(2*7)+(1*0)=115
115 % 10 = 5
So 17159-70-5 is a valid CAS Registry Number.

New methylene homologation method for cyclic ketones

Liu, Huaqing,Sun, Chunrui,Lee, Nam-Kyu,Henry, Roger F.,Lee, Daesung

, p. 11889 - 11893 (2012)

Teaching new tricks to an old dog: By intercepting adducts between ketones and lithium trimethylsilyldiazomethane, a new Tiffeneau-Demjanov type methylene homologation could be realized in a single-step operation. Among proton sources and Lewis acids, silica gel was found to be the most effective reagent for the protonation of intermediates and their subsequent ring expansion (see scheme). Copyright
