Check Digit Verification of cas no

The CAS Registry Mumber 122491-18-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,2,4,9 and 1 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 122491-18:
(8*1)+(7*2)+(6*2)+(5*4)+(4*9)+(3*1)+(2*1)+(1*8)=103
103 % 10 = 3
So 122491-18-3 is a valid CAS Registry Number.

In(+3) as a chemoselectivity switch for TMM-PDL2 cycloadditions to ynones

Trost, Barry M.,Sharma, Sunaina,Schmidt, Thomas

, p. 7183 - 7186 (1993)

The previous inability to effect palladium catalyzed cycloadditions of 2-trimethylsilylmethallyl acetate to the carbonyl group of ynones is rectified by the employment of indium acetylacetonoate as a co-catalyst.

Palladium-Catalyzed Trimethylenemethane Reaction To Form Methylenetetrahydrofurans. Aldehyde and Ketone Substrates and the Tin Effect

Trost, Barry M.,King, Steven A.,Schmidt, Thomas

, p. 5902 - 5915 (2007/10/02)

The palladium-catalyzed trimethylenemethane (TMM) cycloaddition of carbonyl compounds has been shown to have a strong dependence upon the presence of cocatalysts such as tri-n-butyltin acetate, di-n-butyltin diacetate, or trimethyltin acetate.High-yieldin
