4-Nitrophenyl beta-D-galactopyranoside is a chemical compound used as a substrate for the detection and measurement of beta-galactosidase activity. It is a synthetic, chromogenic substrate that is cleaved by the enzyme beta-galactosidase to produce a yellow-colored product, 4-nitrophenol. 4-Nitrophenyl beta-D-galactopyranoside is commonly used in molecular biology and biochemistry experiments to study gene expression and protein function. It is also utilized in diagnostic tests for the detection of lactose-fermenting bacteria and as a pharmaceutical intermediate in the synthesis of various galactosylated compounds. Additionally, 4-nitrophenyl beta-D-galactopyranoside is considered a non-hazardous chemical and is safe to handle when used according to proper laboratory procedures.
Check Digit Verification of cas no
The CAS Registry Mumber 200422-18-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,0,4,2 and 2 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 200422-18:
(8*2)+(7*0)+(6*0)+(5*4)+(4*2)+(3*2)+(2*1)+(1*8)=60
60 % 10 = 0
So 200422-18-0 is a valid CAS Registry Number.
