Triethenylborane, also known as triethylborane or (C2H5)3B, is an organoborane compound that consists of a boron atom bonded to three ethyl groups. It is a colorless, flammable, and highly reactive liquid with a strong, pungent odor. Triethenylborane is widely used as a reducing agent in organic synthesis, particularly in the reduction of carbonyl compounds to alcohols, and as a catalyst in various chemical reactions. Due to its high reactivity, it must be handled with extreme caution, as it can ignite spontaneously in air and is toxic by inhalation, ingestion, and skin contact.
The CAS Registry Mumber 7217-01-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,2,1 and 7 respectively; the second part has 2 digits, 0 and 1 respectively. Calculate Digit Verification of CAS Registry Number 7217-01: (6*7)+(5*2)+(4*1)+(3*7)+(2*0)+(1*1)=78 78 % 10 = 8 So 7217-01-8 is a valid CAS Registry Number.
