Check Digit Verification of cas no
The CAS Registry Mumber 111650-03-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,1,6,5 and 0 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 111650-03:
(8*1)+(7*1)+(6*1)+(5*6)+(4*5)+(3*0)+(2*0)+(1*3)=74
74 % 10 = 4
So 111650-03-4 is a valid CAS Registry Number.

OXIDATIVE DIMERIZATION OF 4-(3,5-DI-tert-BUTYL-4-HYDROXYPHENYL)BUTAN-2-ONE
Titova, T. F.,Krysin, A. P.
, p. 540 - 543 (2007/10/02)
The oxidation of 4-(3,5-dialkyl-4-hydroxyphenyl)butan-2-ones (alkyl=CH3, tert-C4H9) with potassium hexacyanoferrate(III) in the presence of potassium hydroxide leads to dimeric methylenequinones.In the case of the tert-butyl derivative this process is acc
