Triphenyl-<2-nitro-benzyl>-silan, also known as (2-nitrobenzyl)triphenylsilane, is an organosilicon compound with the chemical formula C25H21NO2Si. It is a colorless to pale yellow crystalline solid that is sensitive to air and moisture. Triphenyl-<2-nitro-benzyl>-silan is characterized by a triphenylsilyl group (SiPh3) attached to a 2-nitrobenzyl moiety, which contains a nitro group (NO2) at the 2-position of the benzene ring. Triphenyl-<2-nitro-benzyl>-silan is used as a reagent in organic synthesis, particularly in the formation of carbon-silicon bonds and as a protecting group in the synthesis of various organic compounds. Due to its sensitivity, it is typically handled under an inert atmosphere and stored away from light and heat.

Check Digit Verification of cas no

The CAS Registry Mumber 1251-06-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,2,5 and 1 respectively; the second part has 2 digits, 0 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1251-06:
(6*1)+(5*2)+(4*5)+(3*1)+(2*0)+(1*6)=45
45 % 10 = 5
So 1251-06-5 is a valid CAS Registry Number.
