135875-52-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 135875-52-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,5,8,7 and 5 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 135875-52:
(8*1)+(7*3)+(6*5)+(5*8)+(4*7)+(3*5)+(2*5)+(1*2)=154
154 % 10 = 4
So 135875-52-4 is a valid CAS Registry Number.

Facile syntheses and rearrangements of peptide derived β-lactams
Farouz,Miller
, p. 3305 - 3308 (2007/10/02)
Stereoselective aldol condensation of a 4,5-diphenyl-oxazolin-2-one (Ox) glycine provided α-amino-β-hydroxy acid 4, which, after coupling with phenylglycine derivatives, was directly cyclized to β-lactams. Ozonolysis cleaved both the Ox and isopropylidene
