Silane, dichlorobis(1-methylpropoxy)-, also known as dichlorobis(2-methylpropoxy)silane or (CH3)3CCH2OSiCl2H, is an organosilicon compound with the molecular formula C5H12Cl2OSi. It is a colorless liquid with a pungent odor and is soluble in organic solvents. This chemical is primarily used as a coupling agent in the production of composite materials, particularly in the reinforcement of glass fibers with resins, to improve the adhesion between the fiber and the matrix. It is also employed as a cross-linking agent in the synthesis of silicone rubber and as a silylating agent in organic synthesis. Due to its reactivity with moisture, it is sensitive to air and moisture, and therefore, it must be stored and handled under anhydrous conditions.

6421-40-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 6421-40-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,4,2 and 1 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 6421-40:
(6*6)+(5*4)+(4*2)+(3*1)+(2*4)+(1*0)=75
75 % 10 = 5
So 6421-40-5 is a valid CAS Registry Number.
