Check Digit Verification of cas no

The CAS Registry Mumber 821770-27-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,2,1,7,7 and 0 respectively; the second part has 2 digits, 2 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 821770-27:
(8*8)+(7*2)+(6*1)+(5*7)+(4*7)+(3*0)+(2*2)+(1*7)=158
158 % 10 = 8
So 821770-27-8 is a valid CAS Registry Number.

Diphenylphosphinoyl-mediated synthesis of ketones

Fox, David J.,Pedersen, Daniel Sejer,Warren, Stuart

, p. 3102 - 3107 (2008/02/14)

α-Diphenylphosphinoyl ketones are selectively and sequentially alkylated at the α-position. Double lithiation and selective alkylation occurs at the less stabilised γ-position. Dephosphinoylation of the alkylation products gives ketones. Mono-alkylation is selective, highly crystalline intermediates are formed and a one-pot strategy is possible. The method is ideally suited for the preparation of acid-sensitive ketones. The Royal Society of Chemistry 2006.
