Check Digit Verification of cas no

The CAS Registry Mumber 3840-23-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,8,4 and 0 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 3840-23:
(6*3)+(5*8)+(4*4)+(3*0)+(2*2)+(1*3)=81
81 % 10 = 1
So 3840-23-1 is a valid CAS Registry Number.

Method for Preparing Diureido Compounds

-

Paragraph 0037; 0056-0058, (2016/12/22)

The present invention relates to a method for producing diureido by making diamine having 2 to 13 carbon atoms react with urea. The producing method uses alcohol having 3 to 12 carbon atoms as a reaction solvent and uses tetraalkylammonium hydroxide as a catalyst. According to the producing method of the present invention, the diureido can be produced in a high yield and in a short time.COPYRIGHT KIPO 2016
