General Description
1-Butanethiol, 4-[4-[(1E)-phenylazo]phenoxy]- (9CI) is a chemical compound that contains both a thiol (sulfhydryl) group and a phenylazo group. The thiol group consists of a sulfur atom bonded to a carbon atom, giving the compound its distinct odor. The phenylazo group consists of a nitrogen molecule double-bonded to a carbon atom, bonded to a phenyl (aromatic) ring. This chemical compound is often used in the production of dyes and pigments, as well as in the synthesis of pharmaceuticals and agricultural chemicals. It may also be used as a chemical intermediate in various industrial processes. Due to the presence of the thiol group, it is important to handle this compound with care, as it can be highly reactive and toxic if not properly managed.
Check Digit Verification of cas no
The CAS Registry Mumber 220473-94-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,0,4,7 and 3 respectively; the second part has 2 digits, 9 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 220473-94:
(8*2)+(7*2)+(6*0)+(5*4)+(4*7)+(3*3)+(2*9)+(1*4)=109
109 % 10 = 9
So 220473-94-9 is a valid CAS Registry Number.
