Check Digit Verification of cas no

The CAS Registry Mumber 20129-52-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,0,1,2 and 9 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 20129-52:
(7*2)+(6*0)+(5*1)+(4*2)+(3*9)+(2*5)+(1*2)=66
66 % 10 = 6
So 20129-52-6 is a valid CAS Registry Number.

Selective fries rearrangement catalyzed by zinc powder

Paul, Satya,Gupta, Monika

, p. 1789 - 1792 (2004)

Zinc powder in the presence of N,N-dimethylformamide efficiently catalyzes the selective Fries rearrangement of acetylated phenols under microwave heating or with conventional heating using an oil bath. In some cases different products were obtained using microwave heating and conventional heating. Selective migration of the acyl group has been noted with good yields.

PHOTO-FRIES REARRANGEMENT: REARRANGEMENT OF ACETOXYBENZENE DERIVATIVES
