Check Digit Verification of cas no

The CAS Registry Mumber 120419-76-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,0,4,1 and 9 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 120419-76:
(8*1)+(7*2)+(6*0)+(5*4)+(4*1)+(3*9)+(2*7)+(1*6)=93
93 % 10 = 3
So 120419-76-3 is a valid CAS Registry Number.

TiCl4-MEDIATED REACTIONS OF SILYL KETENE ACETALS DERIVED FROM N-METHYLEPHEDRINE ESTERS: ASYMMETRIC SYNTHESIS OF β-LACTAMS

Gennari, Cesare,Schimperna, Giuliana,Venturini, Isabella

, p. 4221 - 4232 (2007/10/02)

TiCl4 mediated addition of silyl ketene acetals derived from N-methylephedrine esters to various aldehydes and imines was used as the key-step in the enantio- and diastereo-controlled synthesis of β-lactams.Thus 3,4-trans and cis substituted-2-azetidinone
