Check Digit Verification of cas no

The CAS Registry Mumber 959925-23-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,5,9,9,2 and 5 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 959925-23:
(8*9)+(7*5)+(6*9)+(5*9)+(4*2)+(3*5)+(2*2)+(1*3)=236
236 % 10 = 6
So 959925-23-6 is a valid CAS Registry Number.

Synthesis and structural characterization of the bis(diisopropylamino)boron enolate of tert-butyl methyl ketone

Ma, Lili,Hopson, Russell,Li, Deyu,Zhang, Yong,Williard, Paul G.

, p. 5834 - 5839 (2008/10/09)

Lithium, sodium, and potassium enolates reacted with bisaminoboron halides to give bisaminoboron enolates 1a-5c. Specifically, the potassium enolate of tert-butyl methyl ketone reacted with bis-(diisopropylamino)boron chloride in THF at room temperature within 1h to give the bis(diisopropylamino)-boron enolate of tert-butyl methyl ketone (3b) in 61-84% isolated yields. Under similar conditions, the reactivity is highly dependent on the metal employed to generate enolates (K > Na > Li) as well as the nitrogen substituents in the bisaminoboron halides (iPr > Et > TMS). This latter observation is a compromise between the boron-nitrogen resonance and the steric effect. The structural information of enolate 3b was studied in detail. Unlike the aggregated alkali-metal enolates, this boron enolate exists exclusively as a monomer in both the solid and solution states, as identified by X-ray and diffusion-ordered NMR.
