Benzoyl chloride, 4,4'-methylenebis-, also known as methylenebis(benzoyl chloride) or MBC, is an organic compound with the chemical formula C15H10Cl2O2. It is a white crystalline solid that is widely used as a cross-linking agent in the production of polyurethane foams and as a hardener in the manufacturing of unsaturated polyester resins. MBC is synthesized by the reaction of benzoic acid with formaldehyde and phosphorus oxychloride. It is a hazardous substance, classified as corrosive and harmful, and requires proper handling and storage to prevent exposure and environmental contamination.

3268-26-6 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 3268-26-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,2,6 and 8 respectively; the second part has 2 digits, 2 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 3268-26:
(6*3)+(5*2)+(4*6)+(3*8)+(2*2)+(1*6)=86
86 % 10 = 6
So 3268-26-6 is a valid CAS Registry Number.
