4-[[2-methoxy-5-methyl-4-(phenylazo)phenyl]azo]phenol is a complex organic compound with the molecular formula C21H18N4O2. It is characterized by a phenol core, which is a benzene ring with a hydroxyl group attached. The molecule features a 2-methoxy-5-methyl-4-(phenylazo)phenyl group as a substituent on the phenol, which adds a methoxy group at the 2-position, a methyl group at the 5-position, and a phenylazo group at the 4-position. The phenylazo group itself is a phenyl ring connected to the main structure through an azo group (-N=N-). 4-[[2-methoxy-5-methyl-4-(phenylazo)phenyl]azo]phenol is known for its vibrant color and is often used in the synthesis of dyes and pigments due to its chromophoric properties. The specific arrangement of these functional groups contributes to its chemical reactivity and potential applications in various industrial processes.

6657-00-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 6657-00-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,6,5 and 7 respectively; the second part has 2 digits, 0 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 6657-00:
(6*6)+(5*6)+(4*5)+(3*7)+(2*0)+(1*0)=107
107 % 10 = 7
So 6657-00-7 is a valid CAS Registry Number.
