75234-20-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 75234-20-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,5,2,3 and 4 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 75234-20:
(7*7)+(6*5)+(5*2)+(4*3)+(3*4)+(2*2)+(1*0)=117
117 % 10 = 7
So 75234-20-7 is a valid CAS Registry Number.

Base-Induced Conversions of ? Cycloadducts from Azaheptafulvenes and Monosubstituted Ketenes to (Z)-α-Substituted Cinnamamides
Dean, Barry D.,Truce, William E.
, p. 5429 - 5430 (2007/10/02)
The ? cycloadducts from azaheptafulvenes and monosubstituted ketenes rearrange upon treatment with base to give in good yields the amide derivatives of the (Z)-α-substituted cinnammic acids.
