Check Digit Verification of cas no

The CAS Registry Mumber 31843-92-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,1,8,4 and 3 respectively; the second part has 2 digits, 9 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 31843-92:
(7*3)+(6*1)+(5*8)+(4*4)+(3*3)+(2*9)+(1*2)=112
112 % 10 = 2
So 31843-92-2 is a valid CAS Registry Number.

Reaction of enol ethers with the I2-H2O2 system: Synthesis of 2-iodo-1-methoxy hydroperoxides and their deperoxidation and demethoxylation to 2-iodo ketones

Terent'ev, Alexander O.,Borisov, Alexander M.,Platonov, Maxim M.,Starikova, Zoya A.,Chernyshev, Vladimir V.,Nikishin, Gennady I.

experimental part, p. 4159 - 4166 (2011/03/18)

The reaction of enol ethers with the I2-H2O 2 system in diethyl ether affords 2-iodo ketones and the previously unknown 2-iodo-1-methoxy hydroperoxides. In the presence of the I 2-H2O2 system, the latter compounds undergo deperoxidation and demethoxylation to form 2-iodo ketones. The reaction conditions were found for the synthesis of 2-iodo ketones from enol ethers in 67-94% yields. Georg Thieme Verlag Stuttgart - New York.
