123846-91-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 123846-91-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,3,8,4 and 6 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 123846-91:
(8*1)+(7*2)+(6*3)+(5*8)+(4*4)+(3*6)+(2*9)+(1*1)=133
133 % 10 = 3
So 123846-91-3 is a valid CAS Registry Number.

A simple procedure for the synthesis of pyrrole-3,4-diacetic esters and N-derivatives thereof consists of the oxidative alkoxycarbonylation of dipropargylamine or N-derivatives to give 3,4-bis(alkoxycarbonylmethylene)pyrrolidines which can be easily isome
