Check Digit Verification of cas no

The CAS Registry Mumber 1220703-72-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,2,0,7,0 and 3 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1220703-72:
(9*1)+(8*2)+(7*2)+(6*0)+(5*7)+(4*0)+(3*3)+(2*7)+(1*2)=99
99 % 10 = 9

A Straightforward Three-Component Synthesis of α-Amino Esters Containing a Phenylalanine or a Phenylglycine Scaffold

Haurena, Caroline,Le Gall, Erwan,Sengmany, Stephane,Martens, Thierry,Troupel, Michel

supporting information; experimental part, p. 2645 - 2650 (2010/07/02)

A range of α-amino esters has been synthesized in good to high yields using a straightforward three-component reaction among preformed or in situ generated aromatic or benzylic organozinc reagents, primary or secondary amines, and ethyl glyoxylate. The procedure, which is characterized by its simplicity, allows the concise synthesis of esters bearing a phenylglycine or a phenylalanine scaffold.
