335203-32-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 335203-32-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,3,5,2,0 and 3 respectively; the second part has 2 digits, 3 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 335203-32:
(8*3)+(7*3)+(6*5)+(5*2)+(4*0)+(3*3)+(2*3)+(1*2)=102
102 % 10 = 2
So 335203-32-2 is a valid CAS Registry Number.

α,α-Disubstituted Boron Enolates in the Asymmetric Synthesis of Quaternary Carbon Centers
Burke, E. Diane,Gleason, James L.
, p. 405 - 407 (2007/10/03)
(Equation presented) Reduction of α,α-disubstituted thioglycolate amides with lithium di-tert-butylbiphenylide affords α,α-disubstituted enolates with high Z/E selectivity. Transmetalation of the enolates with dicyclohexylboron bromide facilitates highly
