37074-17-2 Usage
General Description
Heptamethyldisilazane, often abbreviated as HMDS or HMDSN, is an organosilicon compound and hexacoordinate silicon. Its chemical formula is [(CH3)3Si]2NH, which implies that it's a derivative of ammonia. It falls under the category of silylating reagents and comes as a colorless liquid. It’s used primarily for its role as an adhesion promoter in the photolithography process of semiconductor device fabrication. Other application areas include its use as an organic solvent, such as in the removal of photoresist in semiconductor devices, silylation of surfaces, and modifying the surface of stationery phases in gas chromatography. The chemical is flammable, reacts with strong oxidants, and will decompose if heated, releasing hazardous vapor.
Check Digit Verification of cas no
The CAS Registry Mumber 37074-17-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,7,0,7 and 4 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 37074-17:
(7*3)+(6*7)+(5*0)+(4*7)+(3*4)+(2*1)+(1*7)=112
112 % 10 = 2
So 37074-17-2 is a valid CAS Registry Number.
