Check Digit Verification of cas no

The CAS Registry Mumber 29054-20-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,9,0,5 and 4 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 29054-20:
(7*2)+(6*9)+(5*0)+(4*5)+(3*4)+(2*2)+(1*0)=104
104 % 10 = 4
So 29054-20-4 is a valid CAS Registry Number.

Catalytic oxidation of catechins to p-benzoquinones with hydrogen peroxide/methyltrioxorhenium

Bernini, Roberta,Mincione, Enrico,Provenzano, Gianfranco,Fabrizi, Giancarlo

, p. 2993 - 2996 (2005)

New p-benzoquinones were obtained by oxidation of catechin and epicatechin derivatives with the hydrogen peroxide/methyltrioxorhenium catalytic system. Reactions were carried out both in homogeneous and heterogeneous conditions and proceeded with high con
