16778-27-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 16778-27-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,6,7,7 and 8 respectively; the second part has 2 digits, 2 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 16778-27:
(7*1)+(6*6)+(5*7)+(4*7)+(3*8)+(2*2)+(1*7)=141
141 % 10 = 1
So 16778-27-1 is a valid CAS Registry Number.

CYCLISATION DE COMPOSES ETHYLENIQUES PAR ASSISTANCE D'IONS SELENIRANIUMS
Rouessac, Francis,Zamarlik, Henri
, p. 2643 - 2646 (2007/10/02)
Acid-catalyzed cyclization of ethylenic selenolactone 3 derived from homogeranic acid 1 affords one bicyclic lactone 5.This intramolecular rearrangement is induced by a seleniranium ion.
