Check Digit Verification of cas no
The CAS Registry Mumber 119614-41-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,9,6,1 and 4 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 119614-41:
(8*1)+(7*1)+(6*9)+(5*6)+(4*1)+(3*4)+(2*4)+(1*1)=124
124 % 10 = 4
So 119614-41-4 is a valid CAS Registry Number.

A Radical Cyclisation Route to 3-Alkyl Furans. Synthesis of Perillene and Dendrolasin
Srikrishna, Adusumilli,Sunderbabu, Gajendran
, p. 371 - 372 (2007/10/02)
A general three step synthesis of 3-alkyl furans, including Perillene and Dendrolasin, from alk-2-ynyl alcohols is described via radical cyclisation of 2-bromo-1-ethoxyethyl alk-2-ynyl ethers to 2-ethoxy-4-alkylidene tetrahydrofurans.
