141315-54-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 141315-54-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,1,3,1 and 5 respectively; the second part has 2 digits, 5 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 141315-54:
(8*1)+(7*4)+(6*1)+(5*3)+(4*1)+(3*5)+(2*5)+(1*4)=90
90 % 10 = 0
So 141315-54-0 is a valid CAS Registry Number.

Asymmetric cyclopropanation of alkenes catalyzed by a 'chiral wall' porphyrin
O'Malley,Kodadek
, p. 2445 - 2448 (2007/10/02)
The iodorhodium derivative of the 'chiral wall' porphyrin is shown to be an extremely active catalyst for the asymmetric cyclopropanation of alkenes by ethyl diazoacetate. Moderate enantioselectivities are observed. The reaction is unusual in that it prov
