Check Digit Verification of cas no
The CAS Registry Mumber 34183-06-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,4,1,8 and 3 respectively; the second part has 2 digits, 0 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 34183-06:
(7*3)+(6*4)+(5*1)+(4*8)+(3*3)+(2*0)+(1*6)=97
97 % 10 = 7
So 34183-06-7 is a valid CAS Registry Number.

An eco-friendly Co(OAc)2-catalyzed aerobic oxidation of 4-benzylphenols into 4-hydroxybenzophenones

An undecorated Co(OAc)2-catalyzed aerobic oxidation system has been reported that enables direct transformation of 4-benzylphenols into the corresponding 4-hydroxybenzophenones. The procedure is especially suitable for electron-withdrawing group-containing substrates, which are commonly inefficient to conduct this category of oxidation. Based on well-defined p-benzoquinone methides and the confirmed ethereal intermediate, a plausible mechanism was depicted.
