957769-25-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 957769-25-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,5,7,7,6 and 9 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 957769-25:
(8*9)+(7*5)+(6*7)+(5*7)+(4*6)+(3*9)+(2*2)+(1*5)=244
244 % 10 = 4
So 957769-25-4 is a valid CAS Registry Number.

Catalytic enantioselective tautomerization of isolated enols
Fehr, Charles
, p. 7119 - 7121 (2008/09/17)
(Figure Presented) Smells like roses: The catalytic enantioselective ketonization of two isolated enols was successful and made possible the discussion of the important mechanistic implications of these findings. The indirect enolate protonation occurs vi
