Check Digit Verification of cas no

The CAS Registry Mumber 334947-46-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,3,4,9,4 and 7 respectively; the second part has 2 digits, 4 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 334947-46:
(8*3)+(7*3)+(6*4)+(5*9)+(4*4)+(3*7)+(2*4)+(1*6)=165
165 % 10 = 5
So 334947-46-5 is a valid CAS Registry Number.

Synthesis of 2,5-disubstituted tetrahydrofurans catalyzed by palladium(0)

Hara, Osamu,Fujii, Kazushige,Hamada, Yasumasa,Sakagami, Youji

, p. 419 - 424 (2007/10/03)

A stereoselective cyclization of an allylic ester to 2,5-disubstituted tetrahydrofurans catalyzed by palladium(0) is demonstrated. In this cyclization, acetoxy heptenol (6a) having a free hydroxy group prefered trans isomer to cis isomer. By the use of the protected acetoxy heptenol (6b), the cis selectivity was observed. The stereoselectivity was enhanced by the use of DPPIO ligand.
