Check Digit Verification of cas no

The CAS Registry Mumber 1221184-57-1 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,2,1,1,8 and 4 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1221184-57:
(9*1)+(8*2)+(7*2)+(6*1)+(5*1)+(4*8)+(3*4)+(2*5)+(1*7)=111
111 % 10 = 1
So 1221184-57-1 is a valid CAS Registry Number.

A modular synthesis of functionalised phenols enabled by controlled boron speciation

Molloy, John J.,Law, Robert P.,Fyfe, James W. B.,Seath, Ciaran P.,Hirst, David J.,Watson, Allan J. B.

, p. 3093 - 3102 (2015)

A modular synthesis of functionalised biaryl phenols from two boronic acid derivatives has been developed via one-pot Suzuki-Miyaura cross-coupling, chemoselective control of boron solution speciation to generate a reactive boronic ester in situ, and oxidation. The utility of this method has been further demonstrated by application in the synthesis of drug molecules and components of organic electronics, as well as within iterative cross-coupling.
