1,2-Di-tert.-butyl-4,5-dinitro-benzol, also known as 1,2-bis(tert-butyl)-4,5-dinitrobenzene, is an organic compound with the chemical formula C14H18N2O4. It is a yellow crystalline solid that is insoluble in water but soluble in organic solvents. 1,2-Di-tert.-butyl-4,5-dinitro-benzol is characterized by the presence of two tert-butyl groups (C4H9) attached to the 1 and 2 positions of a benzene ring, and two nitro groups (NO2) attached to the 4 and 5 positions. It is often used as a stabilizer for polymers, particularly in the production of polyvinyl chloride (PVC), to prevent degradation caused by heat and light exposure. Due to its chemical structure, it provides effective stabilization by scavenging free radicals and preventing chain scission, thus enhancing the durability and longevity of PVC products.

Check Digit Verification of cas no

The CAS Registry Mumber 1756-30-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,7,5 and 6 respectively; the second part has 2 digits, 3 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1756-30:
(6*1)+(5*7)+(4*5)+(3*6)+(2*3)+(1*0)=85
85 % 10 = 5
So 1756-30-5 is a valid CAS Registry Number.
