1377823-82-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1377823-82-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,7,7,8,2 and 3 respectively; the second part has 2 digits, 8 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1377823-82:
(9*1)+(8*3)+(7*7)+(6*7)+(5*8)+(4*2)+(3*3)+(2*8)+(1*2)=199
199 % 10 = 9
So 1377823-82-9 is a valid CAS Registry Number.

Asymmetric pericyclic cascade approach to spirocyclic oxindoles
Richmond, Edward,Duguet, Nicolas,Slawin, Alexandra M. Z.,Lebl, Tomas,Smith, Andrew D.
, p. 2762 - 2765 (2012/07/14)
The reaction of chiral N-arylnitrones with carbocyclic alkylarylketenes generates spirocyclic oxindoles in good yields and with excellent levels of enantioselectivity (90-99% ee) via a pericyclic cascade process.
