Check Digit Verification of cas no
The CAS Registry Mumber 12138-28-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,2,1,3 and 8 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 12138-28:
(7*1)+(6*2)+(5*1)+(4*3)+(3*8)+(2*2)+(1*8)=72
72 % 10 = 2
So 12138-28-2 is a valid CAS Registry Number.

Reaction of solid SiO with calcium in various ratios at 900°C results in the formation of a mixture of CaO, CaSi and Ca5Si3. When the reaction (in a 1:3 ratio) is carried out at 750°C, CaO and Ca3SiO are formed. The structure of the latter compound, which is erroneously described in the literature as cubic Ca2Si , was determined from powder diffraction data. In the reaction mixtures of solid SiO with strontium or titanium, SrSi, SrSi2 and Ti5Si3 were identified. Reaction with aluminium did not result in the formation of a silicide, but of elemental silicon instead.
