20761-28-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 20761-28-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,0,7,6 and 1 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 20761-28:
(7*2)+(6*0)+(5*7)+(4*6)+(3*1)+(2*2)+(1*8)=88
88 % 10 = 8
So 20761-28-8 is a valid CAS Registry Number.

Silicate Species in Solution. Part 1. Experimental Observations
Glasser, Lesley S.,Lachowski, Eric E.
, p. 393 - 398 (1980)
Changes in the pH or concentration of sodium silicate solutions produce changes in the degree of polymerisation of the silicate species, and these have been followed by the technique of trimethylsilylation.Provided that the pH remains relatively high, abo
