Description
Triphenylmethyl, also known as (C6H5)3C, is an unusual aromatic compound that can exist in various forms, including as an anion, cation, or free radical. It is derived from triphenylcarbinol and can be treated with different substances to produce triphenylmethyl salts, which contain the cation (C6H5)3C+ and crystallize as orange-red solids. The yellow (C6H5)3C– anion is produced by reacting sodium with a solution of triphenylmethyl chloride in ether, while the free radical form is obtained by treating triphenylmethyl chloride with mercury or zinc in the absence of oxygen.

Check Digit Verification of cas no
The CAS Registry Mumber 2216-49-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,2,1 and 6 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 2216-49:
(6*2)+(5*2)+(4*1)+(3*6)+(2*4)+(1*9)=61
61 % 10 = 1
So 2216-49-1 is a valid CAS Registry Number.
