77495-30-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 77495-30-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,7,4,9 and 5 respectively; the second part has 2 digits, 3 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 77495-30:
(7*7)+(6*7)+(5*4)+(4*9)+(3*5)+(2*3)+(1*0)=168
168 % 10 = 8
So 77495-30-8 is a valid CAS Registry Number.

Biomimetic Polyene Cyclizations. Asymmetric Induction during the Acid-Catalyzed Cyclization of Chiral Imines

Demailly, Gilles,Solladie, Guy

, p. 3102 - 3108 (2007/10/02)

This paper reports the details of a basic study showing that an imino function is suitable to initiate acid-catalyzed cyclizations of polyenes, affording high yields of cyclized products.The additional advantage of such a function is to introduce very easily a chirality on the polyene skeleton by the way of a chiral group linked to nitrogen.The extent of asymmetric induction by a chiral phenethyl group on nitrogen is from 36percent to 65percent, according to the monocyclic or bicyclic nature of the substrate.
