2-Methyl-nitroso-amino-benzaldehyd, also known as 2-Methyl-N-nitrosoaniline, is an organic compound with the chemical formula C7H7N3O. It is a yellow crystalline solid that is soluble in organic solvents such as ethanol and acetone. 2--benzaldehyd is a derivative of benzaldehyde, featuring a nitroso group (-NO) and an amino group (-NH2) attached to the 2-position of the benzene ring, with a methyl group (-CH3) at the same position. It is used as an intermediate in the synthesis of various dyes, pharmaceuticals, and other organic compounds. Due to its potential reactivity and the presence of a nitroso group, it should be handled with care, as it may pose health risks and is considered a hazardous substance.
The CAS Registry Mumber 7755-71-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,7,5 and 5 respectively; the second part has 2 digits, 7 and 1 respectively. Calculate Digit Verification of CAS Registry Number 7755-71: (6*7)+(5*7)+(4*5)+(3*5)+(2*7)+(1*1)=127 127 % 10 = 7 So 7755-71-7 is a valid CAS Registry Number.
