Check Digit Verification of cas no

The CAS Registry Mumber 805250-94-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,0,5,2,5 and 0 respectively; the second part has 2 digits, 9 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 805250-94:
(8*8)+(7*0)+(6*5)+(5*2)+(4*5)+(3*0)+(2*9)+(1*4)=146
146 % 10 = 6
So 805250-94-6 is a valid CAS Registry Number.

Synthesis of functionalized 2-alkylidene-tetrahydrofurans based on a [3+2] cyclization/bromination/palladium(0) cross-coupling strategy

Bellur, Esen,Langer, Peter

, p. 4815 - 4828 (2005)

The bromination of 2-alkylidene-tetrahydrofurans and 2-alkylidene- pyrrolidines - readily available through one-pot [3+2] cyclization reactions - afforded 2-alkylidene-1′-bromotetrahydrofurans, 2-alkylidene-3- bromotetrahydrofurans and 2-alkylidene-1′,3-dibromotetrahydrofurans and their pyrrolidine counterparts. 2-Alkylidene-1′-bromotetrahydrofurans were functionalized by performing Suzuki and Heck reactions. 2-Alkylidene-1′, 3-dibromotetrahydrofurans were successfully employed in novel double-Suzuki reactions. Wiley-VCH Verlag GmbH & Co. KGaA, 2005.
