Check Digit Verification of cas no

The CAS Registry Mumber 127127-62-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,7,1,2 and 7 respectively; the second part has 2 digits, 6 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 127127-62:
(8*1)+(7*2)+(6*7)+(5*1)+(4*2)+(3*7)+(2*6)+(1*2)=112
112 % 10 = 2
So 127127-62-2 is a valid CAS Registry Number.

β-Lactams from Ester Enolates and Silylimines: Enantioselective Synthesis of the trans-Carbapenem Antibiotics (+)-PS-5 and (+)-PS-6

Andreoli, Patrizia,Cainelli, Gianfranco,Panunzio, Mauro,Bandini, Elisa,Martelli, Giorgio,Spunta, Giuseppe

, p. 5984 - 5990 (2007/10/02)

A new synthetic route to the antibiotics (+)-PS-5 and (+)-PS-6 is described.The preparation involves a fully stereocontrolled reaction between the enantiomerically pure N-trimethylsilylimine of lactic or mandelic aldehyde and the lithium enolate of the tert-butyl butanoate or tert-butyl isovalerate, respectively.Conversion of the azetidinones obtained to 4-acetoxy derivatives via oxidative cleavage of the hydroxyethyl or hydroxybenzyl side chain and introduction of the necessary appendage in the position 4 of the azetidinone ring, followed by assemlage of the bicyclic ring system, afforded the natural trans-carbapenems (+)-PS-5 and (+)-PS-6.
