348135-64-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 348135-64-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,4,8,1,3 and 5 respectively; the second part has 2 digits, 6 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 348135-64:
(8*3)+(7*4)+(6*8)+(5*1)+(4*3)+(3*5)+(2*6)+(1*4)=148
148 % 10 = 8
So 348135-64-8 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
