73119-34-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 73119-34-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,3,1,1 and 9 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 73119-34:
(7*7)+(6*3)+(5*1)+(4*1)+(3*9)+(2*3)+(1*4)=113
113 % 10 = 3
So 73119-34-3 is a valid CAS Registry Number.

An Easy Procedure for the Preparation of 3-Methylidenetetrahydrofurans from Dimethyl Succinates

Corral, Jose M. Miguel,Gordaliza, Marina,Castro, M. Angeles,Salinero, Miguel A.,Dorado, Jose M.,Feliciano, Arturo San

, p. 154 - 164 (2007/10/03)

A new synthetic proceduree to obtain 3-methylidenetetrahydrofurans is described, in which the methylidene group is generated during the formation of the tetrahydrofuran ring. These are prepared by reduction of differently substituted dimethyl succinates obtained by Stobbe condensation.
