Check Digit Verification of cas no

The CAS Registry Mumber 74184-99-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,4,1,8 and 4 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 74184-99:
(7*7)+(6*4)+(5*1)+(4*8)+(3*4)+(2*9)+(1*9)=149
149 % 10 = 9
So 74184-99-9 is a valid CAS Registry Number.

Transformation of Acyclic Ketones into Aldehydes and Ketones with Substituted Side Chains

Tietze, Lutz-F.,Kinast, Guenther

, p. 451 - 460 (2007/10/02)

Aminomethylation of the acyclic ketones 1/2 leads to the aminoketones 3/4 which give, after reduction, quaternisation and ion exchange or previous reaction with a Grignard reagent, the hydroxyammonium compounds 9/10 and 14, respectively.Flash thermolysis of 9/10 yields the aldehydes 7 and of 14 the ketone 15 in which one side-chain of the educt 2b is substituted by the alkyl group of the Grignard reagent.
