820967-77-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 820967-77-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,2,0,9,6 and 7 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 820967-77:
(8*8)+(7*2)+(6*0)+(5*9)+(4*6)+(3*7)+(2*7)+(1*7)=189
189 % 10 = 9
So 820967-77-9 is a valid CAS Registry Number.

A chiral base desymmetrisation - Ring-closing metathesis route to chiral azaspirocycles: Synthesis of core structures related to pinnaic acid and halichlorine

Huxford, Timothy,Simpkins, Nigel S.

, p. 2295 - 2298 (2007/10/03)

A range of highly functionalised chiral azaspirocycles was synthesised, starting from a piperidine diester that is available in 90% ee from a chiral base desymmetrisation. The approach depends upon the use of Grignard addition reactions or a Claisen rearr
