7453-26-1 Usage

General Description

1,3-Dimethyl-1,1,3,3-tetraphenyldisilazane is a silylating reagent, used for the hydrophobization of glass or silica surfaces.

Check Digit Verification of cas no

The CAS Registry Mumber 7453-26-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,4,5 and 3 respectively; the second part has 2 digits, 2 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 7453-26:
(6*7)+(5*4)+(4*5)+(3*3)+(2*2)+(1*6)=101
101 % 10 = 1
So 7453-26-1 is a valid CAS Registry Number.
