1252192-89-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1252192-89-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,5,2,1,9 and 2 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1252192-89:
(9*1)+(8*2)+(7*5)+(6*2)+(5*1)+(4*9)+(3*2)+(2*8)+(1*9)=144
144 % 10 = 4
So 1252192-89-4 is a valid CAS Registry Number.

Enantioselective conjugate radical addition to α'-phenylsulfonyl enones
Lee, Jin Young,Kim, Sundae,Kim, Sunggak
experimental part, p. 4947 - 4949 (2011/01/04)
Enantioselective conjugate addition reactions of alkyl radicals to α'-phenylsulfonyl enones are described. A bis-oxazoline-zinc triflate complex proved to be an effective catalyst leading to high enantioselectivities and chemical yields.
