1141949-75-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1141949-75-8 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,4,1,9,4 and 9 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1141949-75:
(9*1)+(8*1)+(7*4)+(6*1)+(5*9)+(4*4)+(3*9)+(2*7)+(1*5)=158
158 % 10 = 8
So 1141949-75-8 is a valid CAS Registry Number.

Regioselective synthesis of syn disubstituted dibenzo-30-crown-10 ethers
Piatek, Piotr,Litwin, Aleksandra
experimental part, p. 2285 - 2289 (2009/07/11)
A practical and regioselective synthetic method for the synthesis of syn substituted dibenzo-30-crown-10 ethers is reported. This novel methodology is reported with the syntheses of dibenzo crown ethers bearing nitro, formyl and carbomethoxy groups. The s
