1016982-99-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 1016982-99-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,1,6,9,8 and 2 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1016982-99:
(9*1)+(8*0)+(7*1)+(6*6)+(5*9)+(4*8)+(3*2)+(2*9)+(1*9)=162
162 % 10 = 2
So 1016982-99-2 is a valid CAS Registry Number.

Enantioselective addition of β-functionalized allylboronates to aldehydes and aldimines. Stereocontrolled synthesis of α-methylene-γ-lactones and lactams

Chataigner, Isabelle,Zammattio, Fran?oise,Lebreton, Jacques,Villiéras, Jean

, p. 2441 - 2455 (2008)

We report results regarding the development of condensations of chiral β-alkoxycarbonylallylboronates on aldehydes and imines. These allylboronates add in a highly enantioselective and diastereospecific manner to afford biologically and synthetically useful chiral α-methylene-γ-butyrolactones and lactams. The nature of the electrophile (aldehyde vs imine) is shown to have a dramatic influence on the mechanism of the reaction, probably directing the stereoselectivity of the process through different transition states.
