136118-25-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 136118-25-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,6,1,1 and 8 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 136118-25:
(8*1)+(7*3)+(6*6)+(5*1)+(4*1)+(3*8)+(2*2)+(1*5)=107
107 % 10 = 7
So 136118-25-7 is a valid CAS Registry Number.

Synthesis of optically active α,α-distubstituted β-keto esters via chiral β-enamino esters
Guingant,Hammami
, p. 411 - 414 (2007/10/02)
Michael addition of chiral β-enamino esters to MVK and acrylates promoted by Lewis acids (ZnCl2, MgBr2) or high pressure (11-14 Kbar) afforded, after hydrolytic work-up, α,α-disubstituted β-keto esters in good enantiomeric carbon exc
