Tris(trans-2-methylcyclopentyl)borane, also known as TMCB, is a boron-based organometallic compound with the chemical formula C15H27B. It is a sterically hindered borane, characterized by its three trans-2-methylcyclopentyl groups attached to a central boron atom. TMCB is known for its ability to act as a reducing agent, particularly in the reduction of carbonyl compounds to alcohols. It is also used as a catalyst in various organic reactions, such as the hydroboration of alkenes and alkynes. Due to its stability and reactivity, TMCB has found applications in the synthesis of pharmaceuticals, agrochemicals, and other specialty chemicals.

Check Digit Verification of cas no

The CAS Registry Mumber 40911-83-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,0,9,1 and 1 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 40911-83:
(7*4)+(6*0)+(5*9)+(4*1)+(3*1)+(2*8)+(1*3)=99
99 % 10 = 9
So 40911-83-9 is a valid CAS Registry Number.
