Check Digit Verification of cas no

The CAS Registry Mumber 851990-47-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,5,1,9,9 and 0 respectively; the second part has 2 digits, 4 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 851990-47:
(8*8)+(7*5)+(6*1)+(5*9)+(4*9)+(3*0)+(2*4)+(1*7)=201
201 % 10 = 1
So 851990-47-1 is a valid CAS Registry Number.

A metal-free cycloaddition approach to highly substituted aromatic boronic esters

Moore, Jane E.,York, Mark,Harrity, Joseph P. A.

, p. 860 - 862 (2005)

Alkynylboronates participate in [4+2] benzannulation reactions to furnish highly functionalised aromatic boronic esters, further manipulation of these boronic esters has been achieved via oxidation and Suzuki coupling reactions.
