Check Digit Verification of cas no

The CAS Registry Mumber 1632055-84-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,6,3,2,0,5 and 5 respectively; the second part has 2 digits, 8 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1632055-84:
(9*1)+(8*6)+(7*3)+(6*2)+(5*0)+(4*5)+(3*5)+(2*8)+(1*4)=145
145 % 10 = 5
So 1632055-84-5 is a valid CAS Registry Number.

TBHP/TBAI-promoted oxidative cyclization of o -acylphenols for the construction of 2-aryloxybenzofuran-3(2 H)-ones

Yu, Hui,Zhang, Fengling,Huang, Weihua

supporting information, p. 843 - 846 (2014/04/17)

An efficient metal-free approach to 2-aryloxybenzofuranonefuran-3(2H)-ones has been developed. Using tert-butyl hydroperoxide as oxidant and tetrabutylammonium iodide as catalyst, 2-acylphenols reacted with phenols to provide 2-aminobenzofuran-3(2H)-one d
