The CAS Registry Mumber 40544-16-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,0,5,4 and 4 respectively; the second part has 2 digits, 1 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 40544-16:
(7*4)+(6*0)+(5*5)+(4*4)+(3*4)+(2*1)+(1*6)=89
89 % 10 = 9
So 40544-16-9 is a valid CAS Registry Number.

Novel Synthetic Route to Aryl Alkanes from Aromatic Aldehydes and Ketones. Novel Geminal Dialkylation of the Carbonyl Group of Aromatic Aldehydes and Ketones

Krief, Alain,Clarembeau, M.,Barbeaux, Ph.

, p. 457 - 458 (2007/10/02)

Benzyl-lithiums, readily available from benzyl methyl selenides and alkyl-lithiums, are efficiently alkylated; this reaction allows the geminal dialkylation of the carbonyl groups of aromatic aldehydes and ketones and the geminal aryl-alkylation of aliphatic analogues.
