246031-44-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 246031-44-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,4,6,0,3 and 1 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 246031-44:
(8*2)+(7*4)+(6*6)+(5*0)+(4*3)+(3*1)+(2*4)+(1*4)=107
107 % 10 = 7
So 246031-44-7 is a valid CAS Registry Number.

Highly enantioselective synthesis of substituted piperidines using the chiral lithium amide base approach
Goldspink, Nicholas J.,Simpkins, Nigel S.,Beckmann, Marion
, p. 1292 - 1294 (1999)
The symmetry-breaking enolisation reaction of a meso-piperidine diester using a chiral bis-lithium amide base allows access to alkylated derivatives in highly diastereo- and enantioselective fashion (> 98% ee).
