10043-35-3 Usage
General Description
Boric acid, also known as hydrogen borate, is a weak and monobasic acid of boron, often used as an antiseptic, insecticide, flame retardant, neutron absorber, or precursor to other chemical compounds. With the chemical formula B(OH)3, it contains the elements boron, hydrogen, and oxygen. It naturally occurs in some volcanic spring waters or can be manufactured from borax. It is solid under room temperature, appearing as colorless crystals or a white powder, and can be dissolved in water. Breathing in boric acid can irritate the respiratory system and higher or chronic exposure could bring bigger health risks.
Check Digit Verification of cas no
The CAS Registry Mumber 10043-35-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,0,0,4 and 3 respectively; the second part has 2 digits, 3 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 10043-35:
(7*1)+(6*0)+(5*0)+(4*4)+(3*3)+(2*3)+(1*5)=43
43 % 10 = 3
So 10043-35-3 is a valid CAS Registry Number.

A new polytype of orthoboric acid, H3BO3-3T1
Shuvalov, Robert R.,Burns, Peter C.
, p. i47-i49 (2003)
The crystal structure of H3BO3-3T, a new trigonal polytype of orthoboric acid, consists of sheets of hydrogen-bonded B(OH)3 molecules similar to those found in the triclinic structure of orthoboric acid, H3BO3-2A. In each case, van der Waals forces connect the sheets. However, the stacking sequences of the sheets differ between the two polymorphs. In H3BO3-3T (space group P32), the sheets are stacked in the repeating sequence ABC ..., whereas in H3BO3-2/4 (space group P1), the sheets are stacked in the repeating sequence AB ....
