141694-60-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 141694-60-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,1,6,9 and 4 respectively; the second part has 2 digits, 6 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 141694-60:
(8*1)+(7*4)+(6*1)+(5*6)+(4*9)+(3*4)+(2*6)+(1*0)=132
132 % 10 = 2
So 141694-60-2 is a valid CAS Registry Number.

A new approach towards the synthesis of sp3 1,1-diiodoalkanes

Aufauvre, Lionel,Knochel, Paul,Marek, Ilan

, p. 2207 - 2208 (1999)

An easy and straightforward method for the synthesis of gem-diiodo derivatives is reported.

Carbocupration/zinc carbenoid homologation and β-elimination reactions for a new synthesis of allenes - Application to the enantioselective synthesis of chiral allenes by deracemization of sp3-organometallic derivatives

Varghese, Jos P.,Zouev, Irena,Aufauvre, Lionel,Knochel, Paul,Marek, Ilan

, p. 4151 - 4158 (2007/10/03)

A new and straightforward carbocupration/zinc homologation/β-elimination reaction sequence allows the one-pot synthesis of polysubstituted allenes from acetylenic sulfoxides in excellent isolated chemical yields. Secondary zinc carbenoids were used for the homologation reaction, and so a new synthesis of 1,1-diiodoalkanes is described. This methodology also allows the synthesis of chiral allenes through thermodynamic equilibration of secondary organometallic derivatives. Wiley-VCH Verlag GmbH & Co.
