82553-60-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 82553-60-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,2,5,5 and 3 respectively; the second part has 2 digits, 6 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 82553-60:
(7*8)+(6*2)+(5*5)+(4*5)+(3*3)+(2*6)+(1*0)=134
134 % 10 = 4
So 82553-60-4 is a valid CAS Registry Number.

Bismuth triflate catalyzed [1,3] rearrangement of aryl 3-methylbut-2-enyl ethers
Ollevier, Thierry,Mwene-Mbeja, Topwe M.
, p. 3963 - 3966 (2006)
An efficient bismuth triflate catalyzed [1,3] rearrangement of aryl 3-methylbut-2-enyl ethers has been developed. The reaction proceeds rapidly and affords the corresponding para- and ortho-prenylated phenols and naphthols in moderate to good yields (up t
