Check Digit Verification of cas no
The CAS Registry Mumber 133-38-0 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 1,3 and 3 respectively; the second part has 2 digits, 3 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 133-38:
(5*1)+(4*3)+(3*3)+(2*3)+(1*8)=40
40 % 10 = 0
So 133-38-0 is a valid CAS Registry Number.

Mechanism of the Catalytic Oxidation of Tartaric Acid in the Presence of Iron Ions
Sychev, A. Ya.,Duka, G. G.
, p. 43 - 46 (2007/10/02)
The oxidation of tartaric acid by hydrogen peroxide in the presence of iron ions has been studied polarimetrically.A mechanism qualitatively consistent with the kinetics of the oxidation of tartaric acid in both the peroxide (anaerobic) system and the mix
