854000-82-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 854000-82-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,5,4,0,0 and 0 respectively; the second part has 2 digits, 8 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 854000-82:
(8*8)+(7*5)+(6*4)+(5*0)+(4*0)+(3*0)+(2*8)+(1*2)=141
141 % 10 = 1
So 854000-82-1 is a valid CAS Registry Number.

Tightly convoluted polymeric phosphotungstate catalyst: An oxidative cyclization of alkenols and alkenoic acids

Yamada, Yoichi M. A.,Guo, Haiqing,Uozumi, Yasuhiro

, p. 1501 - 1504 (2007)

Equation Presented A tightly convoluted polymeric phosphotungstate catalyst was prepared via ionic assembly of H3PW12O40 and poly(alkylpyridinium). An oxidative cyclization of various alkenols and alkenoic acids was efficiently promoted by the polymeric catalyst in aq H 2O2 in the absence of organic solvents to afford the corresponding cyclic ethers and lactones in high yield. The catalyst was reused four times without loss of catalytic activity.
