Check Digit Verification of cas no

The CAS Registry Mumber 1083302-78-6 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,8,3,3,0 and 2 respectively; the second part has 2 digits, 7 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1083302-78:
(9*1)+(8*0)+(7*8)+(6*3)+(5*3)+(4*0)+(3*2)+(2*7)+(1*8)=126
126 % 10 = 6
So 1083302-78-6 is a valid CAS Registry Number.

Concise stereoselective synthesis of (-)-podophyllotoxin by an intermolecular iron(III)-catalyzed Friedel-Crafts alkylation

Stadler, Daniel,Bach, Thorsten

supporting information; scheme or table, p. 7557 - 7559 (2009/03/12)

(Chemical Equation Presented) Without further ado, the building blocks 1-3 were combined in three C-C bond-forming reactions to provide the enantiomerically pure natural product (-)-podophyllotoxin (4). The stereogenic center at C1 was generated in the key reaction, a diastereoselective iron(III)-catalyzed intermolecular Friedel-Crafts alkylation.
