38011-83-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 38011-83-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,8,0,1 and 1 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 38011-83:
(7*3)+(6*8)+(5*0)+(4*1)+(3*1)+(2*8)+(1*3)=95
95 % 10 = 5
So 38011-83-5 is a valid CAS Registry Number.

Enantioselective, Lewis Base-Catalyzed Sulfenocyclization of Polyenes

Tao, Zhonglin,Robb, Kevin A.,Zhao, Kuo,Denmark, Scott E.

supporting information, p. 3569 - 3573 (2018/03/21)

A sulfenium-ion-initiated, catalytic, enantioselective polyene cyclization is described. Homogeranylarenes and ortho-geranylphenols undergo polycyclization in good yield, diastereoselectivity, and enantioselectivity. The stereodetermining step is the generation of an enantiomerically enriched thiiranium ion from a terminal alkene and a sulfenylating agent in the presence of a chiral Lewis basic catalyst. The use of hexafluoroisopropyl alcohol as the solvent is crucial to obtain good yields. The thioether moiety resulting from the reaction can be subsequently transformed into diverse oxygen and carbon functionality postcyclization. The utility of this method is demonstrated by the enantioselective syntheses of (+)-ferruginol and (+)-hinokiol.
