104898-11-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 104898-11-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,4,8,9 and 8 respectively; the second part has 2 digits, 1 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 104898-11:
(8*1)+(7*0)+(6*4)+(5*8)+(4*9)+(3*8)+(2*1)+(1*1)=135
135 % 10 = 5
So 104898-11-5 is a valid CAS Registry Number.

ENANTIOSELECTIVE MICHAEL REACTIONS. STEREOSELECTIVE ADDITION OF ENOLATES OF PHENMENTHOL ESTERS TO CROTONATES.
Corey, E. J.,Peterson, Richard T.
, p. 5025 - 5028 (2007/10/02)
A method is described for enantioselective synthesis which is based on the stereoselective Michael addition of phenmenthol enolates such as 5 to E-crotonate esters.A stereomechanistic rationale is presented.
