Check Digit Verification of cas no

The CAS Registry Mumber 501419-30-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,0,1,4,1 and 9 respectively; the second part has 2 digits, 3 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 501419-30:
(8*5)+(7*0)+(6*1)+(5*4)+(4*1)+(3*9)+(2*3)+(1*0)=103
103 % 10 = 3
So 501419-30-3 is a valid CAS Registry Number.

Enantioselective total synthesis of borrelidin

Duffey, Matthew O.,LeTiran, Arnaud,Morken, James P.

, p. 1458 - 1459 (2007/10/03)

The first total synthesis of the natural product borrelidin is described. The propionate fragment of the molecule was concisely synthesized through catalytic enantioselective reductive aldol reactions, a catalytic Negishi coupling, and a catalytic directed hydrogenation. The propionate segment was then fused to the vinyl iodide fragment through a catalytic Sonogashira coupling. Subsequent catalytic hydrostannylation and catalytic cyanation allowed access to the target structure. Copyright
