Urea, methyl[[[(methylamino)carbonyl]amino]methylene]-, also known as N,N'-dimethyl-N-ureylenediamine or DMDU, is an organic compound with the chemical formula C4H10N4O. It is a derivative of urea, featuring a urea group (-NH2-CO-NH2) with two methyl groups attached to the nitrogen atoms. DMDU is a colorless, crystalline solid that is soluble in water and various organic solvents. It is primarily used as a crosslinking agent in the production of polyurethane foams, providing improved mechanical properties and dimensional stability. Additionally, DMDU has applications in the synthesis of other chemicals and as a stabilizer in various industrial processes.

Check Digit Verification of cas no

The CAS Registry Mumber 65906-68-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,5,9,0 and 6 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 65906-68:
(7*6)+(6*5)+(5*9)+(4*0)+(3*6)+(2*6)+(1*8)=155
155 % 10 = 5
So 65906-68-5 is a valid CAS Registry Number.
