8-Borononaphthalene-1-carboxylic acid, also known as 8-Borono-1-naphthoesaeure, is a chemical compound with the molecular formula C11H9BO3. It is a boron-containing derivative of naphthalene-1-carboxylic acid, featuring a boron atom attached to the 8-position of the naphthalene ring. 8-Borono-1-naphthoesaeure is of interest in the field of boron neutron capture therapy (BNCT), a targeted radiation therapy for treating certain types of cancer. In BNCT, 8-Borono-1-naphthoesaeure is used as a boron carrier, delivering boron-10 atoms to tumor cells, which then capture neutrons and emit high-energy particles that destroy the cancer cells. The compound's ability to selectively accumulate in tumor tissues makes it a promising candidate for this therapeutic approach.
The CAS Registry Mumber 3965-09-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,9,6 and 5 respectively; the second part has 2 digits, 0 and 9 respectively. Calculate Digit Verification of CAS Registry Number 3965-09: (6*3)+(5*9)+(4*6)+(3*5)+(2*0)+(1*9)=111 111 % 10 = 1 So 3965-09-1 is a valid CAS Registry Number.
