Check Digit Verification of cas no

The CAS Registry Mumber 756893-81-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 7,5,6,8,9 and 3 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 756893-81:
(8*7)+(7*5)+(6*6)+(5*8)+(4*9)+(3*3)+(2*8)+(1*1)=229
229 % 10 = 9
So 756893-81-9 is a valid CAS Registry Number.

The utility of the classical and oxidative Heck reactions in natural product synthesis: Studies directed toward the total synthesis of dragmacidin F

Garg, Neil K.,Caspi, Daniel D.,Stoltz, Brian M.

, p. 3081 - 3087 (2008/02/13)

The syntheses of complex pyrrole-fused [3.3.1] and [3.3.2] bicycles using classical and oxidative Heck cyclizations are described. While both [3.3.1] and [3.2.2] bicyclic products are formed in the classical Heck reaction, the oxidative Heck cyclization r

The total synthesis of (+)-dragmacidin F

Garg, Neil K.,Caspi, Daniel D.,Stoltz, Brian M.

, p. 9552 - 9553 (2007/10/03)

The first total synthesis of (+)-dragmacidin F has been accomplished, establishing the absolute configuration of this biologically important, antiviral marine alkaloid. The convergent route described features a palladium-mediated oxidative pyrrole carbocy
