Therefore, the sequence [2.0.0.0.2.1.1.1] is obtained. In the example on the right, there are two spiroatoms, so the name dispiro starts. In the first terminal ring, there are two atoms, indicating the name dispiro[2. Next, there are one and four atoms in the other terminal ring between the two spiroatoms, revealing the name two snails [2.1.3 5 . The second spiroatom, numbered 5, has been added as a path that will encounter the number of atoms after the number of atoms in the terminal ring, the last time adding 9 and 10 atoms between 3 and 5 spiroatoms And then add an alkane having the same number of atoms of the spiro compound, decane, namedispiro [2.1.3 5 .2 3 ] decane revealed by the name.
ດັ່ງນັ້ນ, ລໍາດັບ [2.0.0.0.2.1.1.1] ແມ່ນໄດ້ຮັບ. ໃນຕົວຢ່າງດ້ານຂວາ, ມີສອງ spiroatoms, ດັ່ງນັ້ນຊື່ dispiro ເລີ່ມຕົ້ນ. ໃນແຫວນ terminal ທໍາອິດ, ມີສອງອະຕອມ, ບອກວ່າຊື່ dispiro [2. ຕໍ່ໄປ, ມີຫນຶ່ງແລະສີ່ເອໂຕລທີ່ຢູ່ໃນວົງແຫວນອື່ນ ໆ ລະຫວ່າງສອງ spiroatoms, ສະແດງຊື່ສອງຫອຍ [2.1.3 5. Spiroatom ທີສອງ, numbered 5, ໄດ້ຖືກເພີ່ມເປັນເສັ້ນທາງທີ່ຈະພົບກັບຈໍານວນຂອງປະລໍາມະນູຫຼັງຈາກຈໍານວນຂອງປະລໍາມະນູໃນວົງແຫວນ, ຄັ້ງສຸດທ້າຍເພີ່ມ 9 ແລະ 10 atom ລະຫວ່າງ spiroatoms 3 ແລະ 5 ແລະຫຼັງຈາກນັ້ນເພີ່ມ alkane ມີ ຈໍານວນດຽວກັນຂອງປະລໍາມະນູຂອງປະສົມ spiro, decane, namedispiro [2.1.3 5 .2 3] decane ເປີດເຜີຍໂດຍຊື່.
