1265680-13-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 1265680-13-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,6,5,6,8 and 0 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1265680-13:
(9*1)+(8*2)+(7*6)+(6*5)+(5*6)+(4*8)+(3*0)+(2*1)+(1*3)=164
164 % 10 = 4
So 1265680-13-4 is a valid CAS Registry Number.

Bronsted base-catalyzed tandem isomerization-Michael reactions of alkynes: Synthesis of oxacycles and azacycles

Liu, Hongjun,Feng, Wei,Kee, Choon Wee,Leow, Dasheng,Loh, Wei-Tian,Tan, Choon-Hong

, p. 3373 - 3379 (2010)

An efficient synthesis of oxacycles and azacycles was developed using a Bronsted base-catalyzed tandem alkyne isomerization-Michael reaction sequence. Functionalized 2-alkylidenetetrahydrofurans were prepared by an intramolecular oxy-Michael reaction on a
