103741-08-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 103741-08-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,3,7,4 and 1 respectively; the second part has 2 digits, 0 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 103741-08:
(8*1)+(7*0)+(6*3)+(5*7)+(4*4)+(3*1)+(2*0)+(1*8)=88
88 % 10 = 8
So 103741-08-8 is a valid CAS Registry Number.

Palladium-catalyzed synthesis of 4-oxaspiro[2.4]heptanes via central attack of oxygen nucleophiles to π-allylpalladium intermediates
Shintani, Ryo,Ito, Tomoaki,Hayashi, Tamio
, p. 2410 - 2413 (2012)
A palladium-catalyzed decarboxylative cyclopropanation of γ-methylidene-δ-valerolactones with aromatic aldehydes has been developed to give 4-oxaspiro[2.4]heptanes with high selectivity. The site of nucleophilic attack to a π-allylpalladium intermediate h
