115859-54-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 115859-54-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,5,8,5 and 9 respectively; the second part has 2 digits, 5 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 115859-54:
(8*1)+(7*1)+(6*5)+(5*8)+(4*5)+(3*9)+(2*5)+(1*4)=146
146 % 10 = 6
So 115859-54-6 is a valid CAS Registry Number.

A Mechanistic Study of the Mitsunobu Esterification Reaction
Hughes, D. L.,Reamer, R. A.,Bergan, J. J.,Grabowski, E. J. J.
, p. 6487 - 6491 (2007/10/02)
The three steps of the Mitsunobu reaction were studied in detail for the esterification, with inversion of configuration, of the 2-(hydroxyethyl)azetidinone 1A.In all solvents examined, formation of the adduct between DIAD and PPh3 occurs far more rapidly
