Check Digit Verification of cas no

The CAS Registry Mumber 197149-78-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,7,1,4 and 9 respectively; the second part has 2 digits, 7 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 197149-78:
(8*1)+(7*9)+(6*7)+(5*1)+(4*4)+(3*9)+(2*7)+(1*8)=183
183 % 10 = 3
So 197149-78-3 is a valid CAS Registry Number.

A new and direct approach to functionalized biaryl α-ketophosphonic acids via aqueous Suzuki coupling on solid support

, p. 19 - 22 (2007/10/03)

A new method for the synthesis of functionalized biaryl α-ketophosphonic acids has been developed. The key step involves the use of sodium bromobenzoyl phosphonates to react with polymer-bound boronic acids via microwave-assisted aqueous Suzuki coupling. This approach provides rapid access to a wide range of diverse biaryl analogues containing an α-ketophosphonic acid moiety.
