Check Digit Verification of cas no

The CAS Registry Mumber 2972-89-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,9,7 and 2 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 2972-89:
(6*2)+(5*9)+(4*7)+(3*2)+(2*8)+(1*9)=116
116 % 10 = 6
So 2972-89-6 is a valid CAS Registry Number.

Synthesis of trifluorostyrene derivatives by palladium-catalyzed cross-coupling of lithium trimethoxy(trifluorovinyl)borate with aryl bromides

Duric, Sasa,Schmidt, Bernd M.,Ninnemann, Nina M.,Lentz, Dieter,Tzschucke, C. Christoph

supporting information; experimental part, p. 437 - 441 (2012/02/15)

Fluor-ing it: The stable, crystalline trimethoxy(trifluorovinyl)borate is a convenient reagent for efficiently displacing a bromine atom with a trifluorovinyl group (see scheme). This Suzuki coupling reaction significantly simplifies the route to trifluor
