Check Digit Verification of cas no
The CAS Registry Mumber 2658-06-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,6,5 and 8 respectively; the second part has 2 digits, 0 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 2658-06:
(6*2)+(5*6)+(4*5)+(3*8)+(2*0)+(1*6)=92
92 % 10 = 2
So 2658-06-2 is a valid CAS Registry Number.

A two-step process for the synthesis of various diamide diamines derived from 1,n-diamino benzene compounds is described. The amidation reaction is simple, mild, involves readily available bis(N-acylthiazolidine-2-thione) derivatives as acylating agents and requires only stoichiometric equivalents of diamine and acylating agents.
